Reported here is a new procedure for the synthesis of α-arylpropionic acids 1 in the racemic form, starting from derivatives of aromatic carboxylic acids 2 (i.e., esters), via 1-aryl-2,2,2-tris(alkylsulfanyl)ethanones 4-6, S-alkyl (aryl)bis(alkylsulfanyl)thioacetates 7-9, S-alkyl α-aryl-α-(alkylsulfanyl)thiopropionates 10-12 and S-alkyl α-arylthiopropionates 13-15. Each stage takes place easily and
本文报道了一种合成外消旋形式的 α-芳基丙酸 1 的新方法,从芳族羧酸 2(即酯)的衍生物开始,通过 1-芳基-2,2,2-三(烷基硫烷基)乙酮4-6,S-烷基(芳基)双(烷基硫基)硫代乙酸酯 7-9,S-烷基 α-芳基-α-(烷基硫烷基)硫代丙酸酯 10-12 和 S-烷基 α-芳基硫代丙酸酯 13-15。每个阶段都很容易发生,并且产量总是很高。
