δ-unsaturated amide, prepared by an amide acetal Claisen rearrangement, has been subjected to hydroxy-lactonisation, and reductive cleavage of the corresponding keto-lactone with aluminium amalgam has led to a trisubstituted cyclohexanone derivative with retention of configuration, thus establishing a new method for the stereocontrolled synthesis of 2,3,3-trisubstituted cyclohexanones.
通过酰胺缩醛Claisen重排制备的γ,δ-不饱和酰胺已经进行了羟基内酯化,相应的酮内酯与铝汞齐的还原裂解导致三取代的环己酮衍生物具有构型保留,从而建立了立体控制合成2,3,3-三取代的环己酮的新方法。
