Abstract:

Geldanamycin possesses various biological activities as seen in the NCI 60 cell line panel (13 nM avg., 70 nM SKBr-3 cells). The predominant mode of action providing these unique results arises from the ability of geldanamycin (GA) to bind to the chaperone heat shock protein 90 (Hsp90). Despite its complicated functionality, the first total synthesis of GA was accomplished, which included two new reactions developed specifically to address the stereochemical features. The final step in the synthesis of GA was a demethylation-oxidation sequence to generate the desired para-quinone. This step co

The synthesis of bromochloromethane (BCM) in a batch reactor, using phase transfer catalysis, was investigated. During the synthetic procedure, sodium bromide (100.0g, 0.97mol) along with an excess amount of dichloromethane (265.0g, 3.12 mol) was charged to a reactor containing benzyl triethylammonium chloride (13 mmol), dissolved in 50 ml of water. The bench scale reactions were all carried out in a Parr 4520 bench top pressure reactor coupled to a Parr 4841 temperature controller. The method produced a 50.0 percent yield of the product BCM after a reaction time of 12 to 13 hours. The main ob

Abstract:

2014 - 2015<br>In the great realm of organic synthesis, phase-transfer catalysis (PTC) is a well recognized methodology which plays a key role both in industry and academia research. This process involves reactions that take place between reagents which are located in different phases, for example an inorganic water-soluble reagent and a substrate soluble in the organic phase. Considering the well-defined advantages of asymmetric phase-transfer catalysis as a powerful method for organic synthesis, the aim of this research project is to introduce novel macrocycle systems as new and efficient ca

Abstract:

Gas-expanded liquids (GXL) are a new and benign class of liquid solvents that are intermediate in physical properties between normal liquids and supercritical fluids and therefore may offer advantages in separations, reactions, and advanced materials. Phase-transfer catalysis (PTC) is a powerful tool in chemistry that facilitates interaction and reaction between two or more species present in immiscible phases and offers the ability to eliminate the use of frequently expensive, environmentally undesirable, and difficult to remove polar, aprotic solvents.

Abstract:

The aim of this project was to utilize chiral cation-directed catalysis in the asymmetric synthesis of novel hererocycles. This goal was initially realized by the synthesis of azaindolines in high yields and enantioselectivities (Chapter 2). Extension of this methodology to substrates bearing two stereogenic centres was successful, although control over both diastereoselectivity and enantioselectivity in this process was modest. Finally the synthesis of heterocycles utilizing cation-directed rearrangement processes was examined, with proof of concept obtained for a novel asymmetric cyclization

Abstract:

Phase-transfer catalysts derived from the cinchona alkaloids cinchonine and cinchonidine are widely used in the asymmetric alkylation of substrates bearing moieties that resonance stabilize their enolates. The investigation of α-oxygenated esters revealed decreased α-proton acidity, indicating the oxygen's overall destabilizing effect on enolates by electron-pair repulsion. Alkylation of α-oxygenated aryl ketones with various alkyl halides proved successful with a cinchonidine catalyst, giving products with high yield and enantioselectivity. The resulting compounds were converted to esters thr

Abstract:

博士<br>國立清華大學<br>化學工程學系<br>90<br>The primary objective of this dissertation is to study the oxidation of organic compounds which include epoxidation of olefin and oxidation of alcohol by phase transfer catalyst. The phase transfer catalytic epoxidation of various olefins using the hydrogen peroxide as oxidant in an organic/aqueous two-phase medium was investigated. Epoxides are widely used in various industries, such as curing the ulcer, manufacturing of cleaning reagent, stabilizing polychloroethyl resin and monomer of the epoxy resins etc.. Using sodium hypochlorite as the oxidant, benzaldeh
