Abstract:
The practice of deploying and teaching retrosynthesis is on the cusp of considerable change, which in turn forces practitioners and educators to contemplate whether this impending change will advance or erode the efficiency and elegance of organic synthesis in the future. A short treatise is presented herein that covers the concept of retrosynthesis, along with exemplified methods and theories, and an attempt to comprehend the impact of artificial intelligence in an era when freely and commercially available retrosynthetic and forward synthesis planning programs are increasingly prevalent. Will the computer ever compete with human retrosynthetic design and the art of organic synthesis?

Abstract:
The synthesis of organic compounds, which is central to many areas such as drug discovery, material synthesis and biomolecular chemistry, requires chemists to have years of knowledge and experience. The development of technologies with the potential to learn and support experts in the design of synthetic routes is a half-century-old challenge with an interesting revival in the last decade. In fact, the renewed interest in artificial intelligence (AI), driven mainly by data availability, is profoundly changing the landscape of computer-aided chemical reaction prediction and retrosynthetic analysis. In this article, we briefly review different approaches to predict forward reactions and retrosynthesis, with a strong focus on data-driven ones. While data-driven technologies still need to demonstrate their full potential compared to expert rule-based systems in synthetic chemistry, the acceleration experienced in the last decade is a convincing sign that where we use software today, there will be AI tomorrow. This revolution will help and empower bench chemists, driving the transformation of chemistry towards a high-tech business over the next decades.

Abstract:
paecilodepsipeptide A was first synthesized by retrosynthesis methods. the structures were determined by Mass Spectrometry and NMR spectroscopy, and the anti-tumor activities on human hepatocellular carcinoma cell line (SMMC-7721) and human lymphoma cell line (Raji) were examined by MTT. The result showed that the rate of Paecilodepsipeptide A was 72% by retrosynthesis methods. The structures of the synthesized product were identified by 1H NMR and 13C NMR spectra, which is identical to the natural product. The product has remarkable anti-proliferation activity on SMMC-7721 and Raji, which showed good anti-tumor activity. IC50 was 8.97 μmol/L and 11.13 μmol/L respectively, The total synthesis of Paecilodepsipeptide A is significant to further study its derivatives and develop novel antitumor drugs.

Abstract:
Retrosynthesis has been likened to the game of chess. There are relatively simple rules to learn, but only through experience and practice can a learner acquire the tacit knowledge required for mastery of the subject. This makes it a challenging topic to teach effectively to a large and diverse cohort of learners. Lectures are a good way of transmitting knowledge, but do not provide the engagement and training that is essential in developing a deep understanding of retrosynthesis. Therefore, students tend to struggle to achieve success in this topic. This project aimed to alleviate this problem by producing online learning resources to be combined with traditional face-to-face teaching methods to develop a blended learning approach. These resources included animated videos, quizzes, worked examples and other interactive learning materials. Analysis of examination results and learner feedback showed that the supplementary resources not only improved student performance and understanding, but also provided a more satisfactory learning experience. External evaluation suggested that the learning package has significant potential and development should be continued. The package of learning resources can be viewed online at: people.bath.ac.uk/ch3jhm

Abstract:
Chemical graph generators are software packages to generate computer representations of chemical structures adhering to certain boundary conditions. Their development is a research topic of cheminformatics. Chemical graph generators are used in areas such as virtual library generation in drug design, in molecular design with specified properties, called inverse QSAR/QSPR, as well as in organic synthesis design, retrosynthesis or in systems for computer-assisted structure elucidation (CASE). CASE systems again have regained interest for the structure elucidation of unknowns in computational metabolomics, a current area of computational biology.

Full text
Abstract:
A new protocol for a general synthesis of cyclic polyenes is presented; in this protocol two new concepts are introduced. The first, acetylene stacking, is the generic term covering both the synthesis of a target molecule and the specific retrosynthesis upon which it is based. This retrosynthetic analysis involves conversion of the target molecule, through a series of transannular [ π2s+π2s] valence isomerizations , into a key polycyclobutanoid intermediate (24). This intermediate is cleaved, in turn, through a similar number of [ σ2s+ σ2s] electrocyclic fragmentations, to yield a set of acetylene synthons . The synthetic phase is based on the recombination of the corresponding acetylene synthetic equivalents in a stacking mode which leads to the target molecule by way of the same polycyclobutanoid intermediate (24). To achieve the ordered assembly of the acteylene synthons, in the required stacking mode, it has been necessary to develop the second concept, namely transfer technology. This involves the use of special transfer reagents, to act as synthetic equivalents and provide the molecular equivalent of acetylenes without ever producing acetylenes per se. Similar transfer reagents are described for cyclobutadienes which serves to demonstrate the wider implications of this new concept in organic synthesis. The bridged bicyclic polyene 8-oxatricyclo [4.3.2.01,6]undeca-2,4,10-triene (73), and the heterocycle 2,4,5,7,8-pentamethyl-1H-oxepino[4,5-c]pyrrole-1,3(2H)- dione (91) are used as the target molecules to illustrate this new synthesis protocol involving sets of stacked acetylenes (or cyclobutadienes ) as the synthetic base. The conversion of the oxepin (91) into isomeric oxepins, and the role of their tautomeric benzene oxides, present as equilibrium partners, is discussed.

Abstract:
In this perspective, we highlight recent examples and trends in metabolic engineering and synthetic biology that demonstrate the synthetic potential of enzyme and pathway engineering for natural product discovery. In doing so, we introduce natural paradigms of secondary metabolism whereby simple carbon substrates are combined into complex molecules through “scaffold diversification”, and subsequent “derivatization” of these scaffolds is used to synthesize distinct complex natural products. We provide examples in which modern pathway engineering efforts including combinatorial biosynthesis and biological retrosynthesis can be coupled to directed enzyme evolution and rational enzyme engineering to allow access to the “privileged” chemical space of natural products in industry-proven microbes. Finally, we forecast the potential to produce natural product-like discovery platforms in biological systems that are amenable to single-step discovery, validation, and synthesis for streamlined discovery and production of biologically active agents.

Abstract:
In an integrated controlling system of palm weevil, using of synthetic feromoid is strickly needed. The research is aimed to synthesize pheromone which secreted by the weevil, e.g. 4-methyl-5-nonanol (R. ferrugineus) and 3-methyl-4-octanol (R. schach) through Grignard reagent which formed in situ. The synthesis was proceded by retrosynthesis to determine the precursor, valeraldehyde. The precursor was reacted with Grignard reagent of sec-amyl magnesium bromide (R. ferrugenieus) and sec-butyl magnesium bromide (R. shach) which made in situ. Characterization of the synthetic molecular pheromone was performed by Gas Chromatography-mass spectroscopy and Fourier Transformed Infra Red. The bioassay of the molecule was carried out by olfactometer. The result showed that the conversion of the reactions were 51.28% (4-methyl-5-nonanol) and 85.90% (3-methyl-4-octanol). The character of physico-chemical and bioactivity of the synthetic pheromone are identic with natural pheromones. Keywords: palm weevil, pheromone, grignard reagent

Full text
Abstract:
The influence of non-covalent interactions on the crystal packing of molecules is well documented in the literature. Unlike molecular solids, crystal engineering of non-molecular solids is difficult to interpret as aggregation is complicated by the presence of neutral as well as ionic species and a range of forces operating, from weak hydrogen bonding to strong covalent interactions. In this perspective, we demonstrate for the first time the role of non-bonding interactions in the occurrence of oxide, hydroxide, or chloride linkages in oxides, hydroxychlorides, and chlorides of copper-based minerals and coordination polymers in terms of a mechanistic approach based on supramolecular retrosynthesis. The model proposed here visualizes the crystal nucleus as a supramolecular analogue of a transition state wherein appropriate tectons (chemically reasonable molecules) aggregate through non-bonding forces that can be perceived through well-known supramolecular synthons. The mechanistic approach provides chemical insights into the occurrence of different topologies and solid-state phenomena like polymorphism.
