Chem Commun (Camb). 2023 Apr 4;59(28):4241-4244. doi: 10.1039/d2cc06613k.

Abstract

A palladium-catalyzed gem-difluoroallylation of propargyl sulfonates with gem-difluoroallylboron has been developed. The reaction features synthetic simplicity and high functional group tolerance, affording 3,3-difluoro-skipped 1,5-enynes with high efficiency and regioselectivity. In particular, the resulting products can serve as versatile synthons for diversified transformations, having potential applications in medicinal chemistry.
