A method for the synthesis of bi- and tricyclic amidines has been developed through copper-catalyzed aerobic [3+2]-annulation reaction of N-alkenyl amidines. E.g., in presence of CuI and 2,2′-bipyridine, [3+2]-annulation of amidine PhC(:NH)NHCH2CPh2CH2CPh:CH2, prepared from 2,2,2-trifluoroethyl benzimidate hydrochloride and 2,2,4-triphenyl-4-penten-1-amine, gave 85% bicyclic amidine (I). These cyclic amidines could be converted into monobenzyl-protected vicinal diamines by reduction with lithium aluminum hydride. E.g., reduction of I gave 83% monobenzyl-protected vicinal diamine (II).
