α-NITRO KETONES 7 : SYNTHESIS OF CONJUGATED NITROCYCLOHEXENES

Dampawan, Pimchit,Zajac, Walter W.

, p. 135 - 138 (2007/10/02)

The reduction of 2-nitrocyclohexanones to the 2-nitrocyclohexanols with sodium borohydride followed by treatment of the β-nitroalcohols with sodium hydride and subsequent acidification of the salts leads to the regioselective synthesis of conjugated nitrocyclohexenes from cyclohexanones.
