摘要: α-溴代丙酰氯分别同四氢噻唑-2-硫酮及(R)-四氢噻唑-2-硫酮-4-羧酸乙酯反应得到四氢噻唑-2-α-溴代丙酰硫酯2a及光学活性4-乙氧羰基四氢噻唑-2-α-溴代丙酰硫酯2b.用半经验的量子化学PM3方法研究了反应物和产物的电子结构和反应的焓变,得到反应物1a异构化的过渡态.

关键词: (R)-四氢噻唑-2-硫酮-4-羧酸乙酯, 四氢噻唑-2-&alpha, -溴代丙酰硫酯, 4-乙氧羰基四氢噻唑-2-&alpha, -溴代丙酰硫酯, 电子结构, 反应焓变

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
