, p. 187 - 194 (1993)
N-phenylmaleimides, o-, m- and p-substituted (1) reacted with excess chlorosulfonic acid to give the corresponding sulphonyl chlorides (2-5). These were condensed with amines and phenols to give derivatives (7-29) which underwent hydrolysis or ammonolysis
CHLOROSULFONATION OF N-ARYLMALEIMIDES
Tome, Augusto C.,Cavaleiro, Jose A. S.,Domingues, Fernando M. J.,Cremlyn, Richard J.
, p. 187 - 194 (2007/10/02)
N-Phenylmaleimides, o-, m- and p-substituted (1) react with excess chlorosulfonic acid to give the corresponding sulphonyl chlorides (2-5).These were condensed with amines and phenols to give derivatives (7-29) which underwent hydrolysis or ammonolysis to give respectively the sulfamoyl maleamic acids (31-34) and sulfamoyl maleamides (35-39). Key words: N-arylmaleimides; chlorosulfonation
