Abstract:

Higher carbon chain sugars have gained increased interest recently; they are important building blocks of natural and unnatural products with biological properties. The synthesis of these higher sugar skeletons is commonly known to be achieved with the Wittig methodology which exploits phosphorus ylide chemistry. This method has been successfully used for the synthesis of the higher carbon sugars. The aim of this project was to synthesise ß,ß'-dioxo sugar-derived phosphorus ylides, a new class of ylides, as versatile intermediates to valuable higher carbon sugar derivatives and carbohydrate mi

Trabalho Final de Mestrado Integrado, Ciências Farmacêuticas, Universidade de Lisboa, Faculdade de Farmácia, 2016<br>Invasive candidiasis has become a major global health concern in the past years, due to both the lack of effective systemic antifungals with low drawbacks and the increasing number of multi-drug resistant yeasts. Macrocyclic compounds have been identified as key-points in the correct functioning of a variety of fundamental biological systems; as well have shown highly favourable drug-like proprieties. Thus, in the last decades, macrocyclic scaffold-based pharmaceuticals have bee

碩士<br>國立交通大學<br>應用化學研究所<br>85<br>Several novel diacetal teioxa-cages compounds 4, 9a-9c, 14 and 17 are synthesized in a short sequence. Diacetal trioxa-cage where synthesized from norbornene derivative of bis-endo-diol by utilizing a novel ozonolysis reaction as the key step. Ozonolysis of bicyclo[2.2.1]heptenes 3, 8a-8c, 13 and 16in dichloromethane at -78℃ followed by reduction with dimethyl sulfide gave diacetal oxa-cages 4, 9a-9c, 14 and 17 in moderate yields, respectively.

We studied on facial stereoselectivity of dioxa-cage compounds 9 and 16 by electrophilic reactions, the proportions of the adducts showed that anti- adducts are the major products. The stereochemistry of compound 17 was proved by the X-ray analysis of compound 18. We resoluted optical active compound (+)20, (-)20, (+)22, (-)22 by using chiral auxiliary (1S)-(-)-camphanic chloride, chiral tetraoxa-cage compound (+)41, (-)41, (+)42, (-)42 were synthesized successfully in the

Abstract:

Magister Pharmaceuticae - MPharm<br>Dioxy MP 14 is a locally developed form of stabilized chlorine dioxide in an aqueous medium. It has all the sanitizing properties of chlorine dioxide gas, a neutral compound of chlorine in the +IV oxidation state, which has been used extensively as a non-toxic sterilizing agent with various applications. In this study, Dioxy MP14 was tested in a commercial chicken pen to determine its effectiveness as an environmental sanitizing agent. Control of environmental microbes in a chicken pen is important to ensure healthy birds and optimum egg production. The bioc

Reactions of the monothia-dioxa-cage compounds 20 and 21 with various nucleophiles exclusively gave the corresponding products which were obtained by nucleophilic addition on the carbonyl group from the face anti to the sulfur atom. The major effect of these results may be attributed to the torsional effect.
