Synthesis of substituted indolizines via radical oxidative decarboxylative annulation of 2-(pyridin-2-yl)acetate derivatives with α,β-unsaturated carboxylic acids†
Abstract
A copper mediated radical oxidative annulation of 2-(pyridin-2-yl)acetate derivatives with α,β-unsaturated carboxylic acids is developed. This study offers a new and expedient strategy for the synthesis of useful indolizines in moderate to good yields and exhibits a broad substrate scope and good functional group tolerance.
