Abstract:

The Bull-Hutchings-Quayle (BHQ) reaction is a novel method for the synthesis of 1-(bromo/chloro)napthalenes from 2-allyphenyl-2’,2’,2’-tri(bromo/chloro)acetates. The reaction is also known as Atom Transfer Radical Cyclisation-Benzannulation (ATRC-Benzannulation). The ATRC-Benzannulation of structurally diverse 2-(cyclohex-1-en-1-ylmethyl)phenyl 2’,2’,2’-trichloroacetates in the presence of 1,3bis-(2,6diisopropylphenyl)imidazolium copper(I) chloride [“Nolan NHC-CuCl”] complexes, using microwave or thermolytic methods, afford a range of 9-chloro-1,2,3,4-tetrahydroanthracenes.

Abstract:

Project I. Cinchona alkaloid-derived quaternary ammonium salts have been successfully used as phase-transfer catalysts, particularly in asymmetric alkylations. Our group applied this type of catalyst in the synthesis of β-hydroxy α-amino acids via aldol reactions and discovered that the Park-Jew catalyst afforded good yields and good enantiomeric excess of the syn diasteromers, but negligible diastereoselectivity. This project was therefore focused on the synthesis of novel cinchonidine-derived catalysts with the Park-Jew catalyst as the lead structure. The C3 position of cinchonidine nucleus

Pyrazoles constitute one of the most important classes of heterocyclic compounds due to their interesting chemical and biochemical features. Researchers have studied many pyrazole containing structures for almost over a century in order to investigate the various biological activities possessed by these molecules.

More recently, the exclusive use of copper, as catalyst has gained significant attention in the Sonogashira-type reaction owing to the low cost of copper salts.
