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
描述了盐孢酰胺A的正式合成。通过衍生自d-葡萄糖的环状酮与Me 3 Al的反应,通过底物控制立体选择性地产生了盐孢子酰胺A中的叔醇功能,随后烯丙基三氯乙酰胺酸的Overman重排有效地构成了氮的四取代碳。形成γ-内酰胺,然后引入环己烯基单元,从而形成了水杨酰胺A的Corey中间体。 立体选择性合成-碳水化合物-手性库-重排-周环反应
