Abstract:

The overall approach in the present investigation has been to explore applications of the Morita-Baylis-Hillman (MBH) reaction in asymmetric synthesis and in the continuation of systems with medicinal potential. To this end, a series of varied camphor-derived acrylate esters was prepared to serve as chiral substrates in asymmetric Morita-Baylis- Hillman reactions. Reduction of N-substituted camphor-10-sulfonamides afforded the 3- exo-hydroxy derivatives as the major products. Acylation of the corresponding sodium alkoxides gave the desired 3-exo-acrylate esters, isolation of which was complica

Abstract:

Organic synthesis problems are a common assessment tool in organic chemistry courses, as they give instructors the opportunity to determine students’ ability to integrate and apply their knowledge of reactions and skills learned in the course. However, students often tend to be unsuccessful in solving them, even if they appear to have a strong grasp on other course material. We hypothesized that part of the reasoning behind this issue is because it can be challenging to integrate learning activities into the curriculum that give students the opportunity to apply their knowledge to synthetic pr

In this study, we investigated the potential applications of carbohydrates in the development of new antibiotics. To tackle the problem of multidrug-resistant variants of M. tuberculosis (MDR-TB), we investigated the biosynthesis pathways of trehalose, which has contributed to significant drug resistance. Some new methods were developed for the synthesis of potential inhibitors (6-azido-trehalose and 6,6'-diazido-trehalose) that have been designed to imitate the intermediate molecule (trehalose 6-phosphate, TPP) of OtsA-OtsB pathway.

Abstract:

The stereochemical outcome of the Peterson olefination reaction was studied using o(-trimethylsilylbenzyl carbanion and a series of N-aliphatic/aromatic azomethines. All reactions led stereoselectively to trans-olefins in moderate to low yields. The Peterson intermediate was isolated when neopentylideneaniline was used at room temperature. This intermediate, on treatment with base or acid, gives the corresponding trans-alkene and trimethylsilylphenylmethane, thus providing unambiguous evidence for the reversibility of the first step in the olefination process.

Abstract:

碩士<br>東海大學<br>化學工程學系<br>94<br>Recently, studies attempted to decrease the bone cement curing exotherm. The new PEMA/nBMA bone cement system is chosen to achieve this goal. However, due to the fact that it is weaker in mechanical strength, organic nano-sized clay will be added. This composite system of bone cement/clay is expected to be better than commercial product nowadays in the following ways: 1. low exotherm during cure, 2. viability in adjusting mechanical strength between human bone and prosthesis, and 3. low shrinkage. In this research, a nanocomposites of PMMA/clay was made by melt in

The OLED structure used in this study was ITO/NPB/MADN/Alq3:Ir(piq)3/TPBi/LiF/Al on PET substrate. The white light emission of the device comes from the mixing emission of a blue host emitting layer, a green host emitting layer, and a red guest dopant in the green emitting layer. The device performance has been improved by adding the TPBi layer which forms energy barrier to confine carriers in the emitting laye

By placing the thin films in a microcavity, the photon-exciton strong-coupling phenomenon is able to be observed. The physical structures and optical properties of the J-aggregate thin films fabricated via both layer-by-layer assembly and spin coating are analyzed. We find that the layer-by-layer assembly method produces the most ideal absorption and uniform emissions when c

Abstract:

Research toward the total synthesis of the promising antibiotic lactonamycin is reported. Lactonamycin exhibits a wide range of potentially useful biological activities. Most notable among these, is the potent activity displayed against methicillin-resistant Staphylococcus aureus and vancomycin-resistant Enterococcus. The first reported synthesis of the ABCD-ring system of lactonamycin has been accomplished in nine steps in 15.3% overall yield utilizing a novel tandem cyanide conjugate addition/Dieckmann condensation as the key step. This powerful annulation reaction was developed in a model

As a active layer, the DEDOC thin films are placed in the microcavity. We design the three different cavity length, respectively, 120 nm, 145 nm, 210 nm. From the angle-resolved reflection spectra, we demonstrated the generation of polariton states, well matching with the simulation. Next, from the angle-re
