Nitriles in Organic Synthesis: The Reaction of Cinnamonitriles with Cyclohexanone and Acetylacetone

El-Sakka, I. A.,El-Kousy, S. M.

, p. 345 - 350 (2007/10/02)

The reaction of 1a,b with cyclohexanone afforded hexahydronaphthalene derivatives (3a,b).In contrast to the behaviour of 1a,b, cyclohexanone reacts with 4a-c to yield the propenylidenecyclohexanone derivatives (5a-c).The reaction of 1a with acetylacetone
