The first synthesis of N-alkyl-N-arylthiocarbamoylacetates and acetic acids

Spears, Glen W.,Tsuji, Kiyoshi,Tojo, Takashi,Nishimura, Hiroaki,Ogino, Takashi

, p. 565 - 574 (2007/10/03)

N-Alkyl-N-arylthiocarbamoylacetates, the key intermediates for the synthesis of novel antinephritic agents, have been prepared for the first time. Some of the esters were in turn hydrolyzed to the corresponding acids. An alternative, indirect synthetic route was also developed to prepare some unusual acids.
