摘要

Hypoglycaemic 1-carbamoyl and -thiocarbamoyl-2-imino pyrrolidines. M3A. Compounds of formula (I):- (where R1= Ph opt. substd. by alkyl, alkoxy or halogen; R2= Ph opt. substd. by alkyl, alkoxy or halogen, cycloalkyl, cycloalkenyl; R3=R6=H or lower alkyl; R7= H, alkyl, carbalkoxyalkyl, dialkylaminoalkyl, alkoxyphenyl or alkoxyalkyl; X= O or S). are new compounds having hypoglycaemic activity. Preferred compounds include 1-(N-methoxymethyl)-thiocarbamoyl-2-imino-3,3-diphenyl-5-methyl-p- yrrolidine (X).
