A one-pot, three-step tandem process has been developed for the direct synthesis of functionalised bicyclic [3.3.0], [4.3.0] and [5.3.0] γ-lactams from simple allylic trichloroacetimidates. The process involves a palladium(II) mediated Overman rearrangement followed by the use of Grubbs first generation complex which catalyzes both a ring closing metathesis reaction and a Kharasch cyclization. As well
已经开发了一种一锅三步串联方法,用于从简单的烯丙基三氯乙亚氨酸酯直接合成官能化的双环[3.3.0],[4.3.0]和[5.3.0]γ-内酰胺。该过程涉及钯(II)介导的超人重排,随后使用Grubbs第一代复合物,该复合物既催化开环易位反应,又催化Kharasch环化。除了探索合成一系列功能化的双环γ-内酰胺的方法的范围外,手性的使用钯(II) 还证明了在对映选择性合成双环γ-内酰胺的Overman重排过程中的催化剂。
