摘要

我们设计了一种光催化方法，利用甲基溴乙酸酯和 N-烯丙基溴二氟乙酰胺作为起始材料，通过自由基级联过程，立体选择性地构建了包含 3,3-二氟-γ-内酰胺的三取代烯，收率为 17-93%。反应机理包括单电子转移、5-外-三环化、自由基加成和级联消除。

Photo‐catalyzed Stereospecific Synthesis of Trisubstituted Alkenes Incorporating 3,3‐Difluoro‐γ‐Lactams from Morita‐Baylis‐Hillman Acetates and N‐Allylbromodifluoroacetamides

A photocatalytic methodology has been devised for the stereoselective construction of trisubstituted alkenes incorporating 3,3‐difluoro‐γ‐lactams in 17‐93% yields via a radical cascade process utilizing MBH acetates and N‐allylbromodifluoroacetamides as starting materials. The reaction mechanism involves single‐electron transfer, 5‐exo‐trig cyclization, radical addition, and elimination in a cascade fashion.

期刊介绍： Advanced Synthesis & Catalysis (ASC) is the leading primary journal in organic, organometallic, and applied chemistry. The high impact of ASC can be attributed to the unique focus of the journal, which publishes exciting new results from academic and industrial labs on efficient, practical, and environmentally friendly organic synthesis. While homogeneous, heterogeneous, organic, and enzyme catalysis are key technologies to achieve green synthesis, significant contributions to the same goal by synthesis design, reaction techniques, flow chemistry, and continuous processing, multiphase catalysis, green solvents, catalyst immobilization, and recycling, separation science, and process development are also featured in ASC. The Aims and Scope can be found in the Notice to Authors or on the first page of the table of contents in every issue.
