Abstract:
The double elimination reaction of β-substituted sulfones offers a versatile strategy for synthesis of arylene ethynylene kits containing heteroaromatic rings. A sequence of aldol reaction between α-sulfonyl carbanion and aldehyde, trapping the resulting aldolate to give β-substituted sulfone, and double elimination of this intermediate can be integrated in one pot. This protocol allows thiophene, pyridine, and ferrocene units to be accommodated in phenylene ethynylene arrays.Key words: arylene–ethynylenes, heteroaromatic rings, ferrocene, double elimination, sulfones.

The 2,7-dilithiated substrates of 3,6-dimethylthieno[3,2-b]thiophene, N,N′-dimethylpyrrolo[3,2- b]pyrrole and N-methylthieno[3,2-b]pyrrole were reacted with W(CO)6 to give, after subsequent alkylation with Et3OBF4, the ditungsten biscarbene complexes [(CO)5W{C(OEt)XXC(OEt)} W(CO)5] (XX = condensed heteroaromatic spacers). Sites of attack during the dilithiation of the condensed rings were studied and compared, and the yields of the desired ditungsten biscarbene complexes optimized by changing the reaction conditions according to the role of the heteroatoms in the rings.

Abstract:
The carbon-hydrogen (C-H) bond is a fundamental chemical bond that constitutes organic molecules, and its direct conversion leads to highly efficient molecular synthesis. In recent years, the hydrogen atom transfer (HAT) catalysis using the energy of visible light, has been attracting attention. However, existing methods require the use of photoredox catalysts such as organic molecules with complex structures and expensive metal complexes. In this study, we developed an organocatalytic system that mimics the electron transfer process of enzymes in vivo and promotes functionalization of stable

Abstract:
William Pitt and co-workers have created a virtual exploratory heterocyclic library ‘VEHICLe’ containing over 200 unconquered bicyclic heteroaromatic rings, synthetically feasible with potential medicinal interest. Since the publication of the 22 ‘heteroaromatic rings of the future’ by Pitt in 2009, 15 of them have been successfully synthesized as bicyclic or polycyclic forms and evaluated for applications in both biology and material science. This short review presents the critical synthesis associated with innovative synthetic methodologies of the synthetically conquered ring scaffolds from

Many current therapeutic agents are based on a core structure consisting of a fused ring heteroaromatic polycyclic system. Methodology for the synthesis of a range of these structurally diverse heteroaromatic derivatives is therefore highly desirable and short, high yielding, regioselective and flexible routes to such systems is very important. Our methodology utilises nucleophilic substitution reactions between pentafluoropyridine (PFP) and its derivatives, and various binucleophiles, e.g. The methodology has also been extended to 4-substituted tetrafluoropyridine derivativesand different bin

Nature’s biodiversity is complex and filled with beauty and wonder which are all observable on the macroscopic scale. This exquisiteness of nature’s intricacies are mirrored on the molecular level such that substances, large or small, are assembled to serve as signaling molecules, protective agents, and fundamental composites of higher-order frameworks for the operation and survival of life. Over the years, chemists have isolated and synthesized these molecules, known as natural products, to understand and evaluate their functions in biology and potential for medicinal applications.

Abstract:
Over the past decades, functional group manipulation of aromatic precursors has been a common strategy to access new aromatic compounds. However, these classical methods, such as Friedel-Crafts alkylations and electrophilic/nucleophilic aromatic substitutions, have shown lack of regioselectivity besides the use of activators in excess amounts. To this end, numerous benzannulations to form benzo-fused substrates via Diels-Alder (DA), ring-closing metathesis (RCM), cycloaddition, and transition-metal-promoted processes have been reported.

Heterocyclic compounds are essential in the metabolism of all living cells, and most nitrogen-containing fused heterocyclic compounds with five-membered rings are biologically active. Nitrogen and sulphur-containing heteroaromatic compounds, such as imidazothiazoles and their derivatives, are acknowledged for their biological activity and substantial contributions to medicinal chemistry. Imidazothiazoles are defined by their fused bicyclic structure, merging an imidazole ring (a five-membered ring with two non-adjacent nitrogen atoms) with a thiazole ring (a five-membered ring containing both

This chapter introduces the idea of developing a structured approach to the disconnection of target molecules based on biocatalytic retrosynthesis. The reader will be guided through the various disconnections that are possible, both for acyclic and cyclic systems, in order to gain an understanding of where biocatalysts can be applied in organic synthesis. The various disconnections possible are organised into one of five different groups: (i) acyclic systems: substituted alcohols, amines, carboxylic acids, ketones etc. (1 functional group); (ii) acyclic systems: 1,2-, 1,3-, and 1,4-diols, hydr
