General description

2-(Methylthio)cyclohexanone is a 2-substituted cyclohexanone. The proportion of axial and equatorial conformation has been measured in chloroform by the Eliel method. It suggests that the in chloroform steric effect dominates over polar effect in contributing to the conformational preference. The stereoselectivity of the reduction of 2-(methylthio)cyclohexanone using different hydrides has been studied.

Application

2-(Methylthio)cyclohexanone may be used as a ketone substrate for the synthesis of cyclic nitrones, by reacting with aspergillusol A.
