Abstract: A novel radical cross-coupling/cyclization of 2-(pyridin-2-yl)acetate derivatives and sulfoxonium ylides is developed, which provides a straightforward access to structurally diverse methylthio-substituted indolizine. A series of 1,2,3-trisubstituted indolizines are readily synthesized in modest yields. In this… read more here.
