Abstract

Abstract The title synthesis was achieved by the reaction of t-butoxycarbonylguanidine with 3-bromo-1, 1-dimethoxypropan-2-one as a key step. Starting with 1-tert-butoxycarbonyl-2- tert-butoxycarbonylaminoimidazol-4-carbaldehyde thus obtained expeditious synthesis of oroidin, hymenidin, dispacamide and monobromodispacamide, the representative 2- aminoimidazole alkaloids, was accomplished.
