The stereocontrolled synthesis of a 2,3,3-trisubstituted cyclohexanone involving hydroxylactonisation of a tertiary amide
Abstract
A new method for the stereocontrolled synthesis of 2,3,3-trisubstituted cyclohexanones is reported which involves the first example of hydroxylactonisation of a γ,δ-unsaturated tertiary amide followed by reductive cleavage of the lactone to produce the substituted cyclohexanone.
