Studies on the Reaction and Quantum Chemistry of Thiazolidine 2-thione and (R) Thiazolidine-2-thione-4-carboxylic Ethyl Ester with α-Bromopropylchloride

Abstract

Abstract: Thiazolidine-2-α-bromopropyonyl thiol ester 2a and optically active (R)-thiazolidine-4-ethoxy carbonyl-2-α-bromopropyonyl thiol ester 2b were perpared by the reaction of α-bromopropyonyl chloride with thiazolidine-2-thione and (R) thiazolidine-2-thione-4-carboxylic ethyl ester. The electronic structures of products and reactants were studied by molecular orbital PM3 method. The reaction enthalpies of products and the transition state of reactant 1a were obtained.

Key words: (R)-Thiazolidine-2-thione-4-carboxylic ethyl ester, Thiazolidine-2-α-bromopropyonyl thiol ester, (R)-Thiazolidine-4-ethoxycarbonyl-2-&alpha, bromopropyonyl thiol ester, Electronic structure, Reaction enthalpies
