Addition of Grignard reagents to s-transenaminones derived from 1,3-cycloalkanediones are described. In dichloromethane, addition of phenylmagnesium bromide gave 3-phenyl substituted cycloalkenones. Alkylmagnesium halides underwent multiple addition reactions, giving mixtures of the 3-alkylcycloalkenones and 1,3-dialkyl-3-(dialkylamino)cyclohexenes. In tetrahydrofuran, only the 3-alkylcycloalkenone was obtained.
