A novel synthesis of the 2-amino-1H-imidazol-4-carbaldehyde derivatives and its application to the efficient synthesis of 2-aminoimidazole alkaloids, oroidin, hymenidin, dispacamide, monobromodispacamide, and ageladine A
摘要:
A novel synthesis of 2-amino-1H-imidazol-4-carbaldehyde derivatives was achieved by the reaction of tert-butoxycarbonylguanidine with 3-bromo-1,1-dimethoxypropan-2-one as a key step. The usefulness of the derivatives as building blocks was proved by accomplishing the efficient synthesis of the representative 2-aminoimidazole alkaloids, oroidin, hymenidin, dispacamide, monobromodispacamide, and ageladine A.

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.
