A novel approach to conjugated enone oximes from aliphatic nitro compounds deals with double silylation of N,N-bis(silyloxy) enamines followed by a stereoselective reaction with an ester-stabilized sulfur ylide. The proposed mechanism involves the generation of labile nitrosoalkenes as intermediates, which react with the sulfur ylide to give target enone oximes.

A new convenient procedure for the preparation of a variety of α-hydroxy oximes from available aliphatic nitro compounds via intermediate N,N-bis(siloxy)enamines is presented. The mechanism of the key step, the rearrangement of N,N-bis(siloxy)enamines, is discussed.
