                                    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.
