Abstract

A mild, metal‐free protocol for cascade [4+2] addition‐defluorinative annulation of gem‐difluoroalkenes with alkynes was realized via photoredox catalysis. This method was feasible for a wide range of terminal alkynes, affording the 1,3‐cyclohexadiene derivatives or fluoro‐substituted arenes in moderate to good yields, respectively. The merit of this strategy was demonstrated by the late‐stage functionalization of pharmaceuticals and the synthesis of high‐value‐added complex molecules.

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.
