Visible-light-induced alkoxycarbonylation/cyclization of 1,7-enynes: synthesis of dihydropyranones containing all-carbon quaternary centers
Jian‐Qiang Chen, Qi Chen, Baofu Chen, Jie Wu
Abstract
A photoredox catalyzed radical-triggered tandem cyclization of 1,7-enynes with alkyloxalyl chlorides is developed, leading to dihydropyranones containing all-carbon quaternary centers through alkoxycarbonylation/dicyclization with 1,7-enynes.
