摘要

Because of this importance, many synthetic methods have been developed based on (a) condensation of 2-aminothiophenol with carbonyl compounds such as aldehydes, 12–14 carboxylic acids, 15–17 acid chlorides, 18 or esters; 19 (b) conversion of 2-halo amides into the corresponding thioamides using P 4 S 10 or Lawesson's reagent, but generally not feasible for substrates containing ketone, ester, and amide moieties; 20 (c) cyclization of thioformanilides with the aid of ...
