A general synthesis of 6-azasteroids

2012
The ozonization of 7-ketocholesteryl acetate has yielded 5-keto-5, 7-seco-6-nor-3-cholesten-7-oic acid, an intermediate useful in the preparation of 6-azacholestane. Catalytic hydrogenation converted this intermediate to 5-keto-5,7-seco-6-norcholestan-7-oic acid which, upon treatment with benzyl amine, gave N-benzyl-6-aza-4-cholesten-7-one.
