【Abstract】 The N acetylthiazolidine 2 thione 4 carboxylic acid (2) was obtained through the reaction of acetic anhydride with (R) thiazolidine 2 thione 4 carboxylic acid. Product 2 reacted with benzyl alcohol to produce the corresponding acetic ester and (R) thiazolidine 2 thione 4 carboxylic acid in the presence of K 2CO 3. When the 2 reacted with alcohols in the presence of SOCl 2 the acetic esters and (R) thiazolidine 2 thione 4 carboxylic esters were formed. But the 2 reacted with alcohol in the presence of DCC the (R) N acetylthiazolidine 2 thione 4 carboxylic ester was prepared.更多还原
