PHOTO-INDUCED MOLECULAR TRANSFORMATIONS.PART 87. REGIOSPECIFIC PHOTO-BECKMANN REARRANGEMENT OF STEROIDAL α,β-UNSATURATED KETONE OXIMES: SYNTHESIS OF SOME STEROIDAL ENAMINO LACTAMS

While it is well known that the Beckmann rearrangement of steroidal cyclic α,β-unsaturated ketone oximes lead to the exclusive formation of enone-type lactams regardless of the initial geometry of their hydroxyimino group, the photolysis of three isomeric cholestenone oximes, (E)- and (Z)-cholest-4-en-3-one oximes, (E)-2,2-dimethylcholest-4-en-3-one oxime, and (E)-cholest-5-en-7-one oxime in protic solvents has shown that in each case an enamine-type lactam is the sole product (yield/=33 percent), no enone-type lactam being formed.This regiospecific photo-rearrangement may be of value for the preparation of these enamine-type lactams which cannot be achieved by the Beckmann rearrangement.
