Procedures for the preparation of 2-amino- and 2-arylaminobenzimidazoles were developed, and one of the efficient procedure was applied to the synthesis of preclathridine A, a marine imidazole alkaloid isolated from a sponge.
Photochemical Elimination of Molecular Nitrogen from Phenyl-Substituted 1,4-Dihydro-5-imino-5H-tetrazoles. Products of Phenyl-Substituted Tris(imino)methane Diradicals
