Abstract

A formal synthesis of salinosporamide A is described. The tertiary alcohol function in salinosporamide A was stereoselectively generated via the substrate control by the reaction of a cyclic ketone derived from d-glucose with Me3Al, and subsequent Overman rearrangement of an allylic trichloroacetimidate effectively constructed the tetrasubstituted carbon with nitrogen. Formation of γ-lactam, followed by the introduction of a cyclohexenyl unit furnished the Corey’s intermediate of salinosporamide A.
