摘要

Abstract Acylation of 4-carbamoylimidazolium-5-olate (2) with a variety of acid chlorides produced 4 (5)-carbamoyl-1H-imidazol-5-(4) yl acid carboxylates (3a-j). Treatment of esters 3a, c with sodium hydroxide gave imides, 4a, c. Methylation of 3a and 2 with diazomethane gave the N-3 methyl derivative (6) and a mixture of the N-3, O-dimethyl derivative (9), the N- 1, N-3-dimethyl derivative (10) and the O-methyl derivative (11), respectively. 5- ...
