Enamine chemistry. Part 24. 2,2-versus 2,6-Disubstitution in 2-alkylcyclohexanone enamines. Factors affecting the regioselectivity and stereoselectivity of enamine alkylation and protonation
Abstract
The factors affecting the reversibility and energetics of competing reaction pathways are discussed and shown to provide a rational explanation for the regioselectivity of reaction of 2-substituted cyclohexanone enamines.
