Iridium-catalyzed [(5+1)-1] an-nulation of pyridinium 1,4-zwitterionic thiolates and sulfoxonium ylides: a ver-satile plat-form to in-dolizines

An efficient synthesis of indolizines from pyridinium 1,4-zwitterionic thiolates and sulfoxonium ylides via a formal [(5+1)-1] pathway has been demonstrated. This reaction process involved an Iridium (III)-catalyzed (5+1) annulation, oxidation,...
