Visible-Light-Induced Carbo-2-pyridylation of Electron-Deficient Alkenes with Pyridinium Salts.

Rong-Bin Hu1, Shuai Sun1, Yijin Su1.   

Abstract

A simple and practical visible-light-induced carbo-2-pyridylation of electron-deficient alkenes with readily available N-benzoylmethylpyridinium bromides is reported. More than 40 examples are presented and proceed in greater than 80 % yield (on average) with excellent regio- and diastereoselectivities.
