A flexible radical approach to 5-substituted 4,5-dihydro-3H-pyrido[4,3-b]azepin-2-ones. Some mechanistic observations on the radical cyclisation-aromatisation process
摘要:
Variously substituted novel dihydropyridoazepinones have been prepared by an intermolecular radical addition followed by a radical cyclisation on a pyridine ring. The latter process involved the use of a combination of two different peroxides, an experimental contrivance resulting from a careful product analysis and a better understanding of the cyclisation step.
