The preparation of unsaturated secondary lactams via the palladium-catalyzed cyclization of O-phenyl hydroxamates onto a pendent alkene is reported. This method provides rapid access to a broad range of lactams that are widely useful building blocks in alkaloid synthesis. Mechanistic studies support an aza-Heck-type pathway.
报道了通过钯催化的O-苯基异羟肟酸酯与侧链烯烃环化制备不饱和仲内酰胺的方法。该方法能够快速获得多种内酰胺,这些内酰胺是生物碱合成中广泛使用的有用砌块。机理研究支持氮杂Heck型反应途径。
