Oxidative transformatons of 2-aryl-1,2,3,4,7,8-hexahydroacenaphtho[5,6-bc]azepin-4-ones
摘要:
Reactions of partial (elimination of H-2 from the bimethylene unit) and exhaustive (elimination of 2H(2) from the bimethylene unit and the seven-membered heterocycle) dehydrogenation of 2-aryl-1,2,3,4,7,8-hexahydroacenaphtho[5,6-bc]azepin-4-ones were performed. The effect of the electronic structure of initial and dehydrogenated compounds on their spectral characteristics was discussed. New peri-fused heterocyclic systems were obtained.
