One-Pot Synthesis of Indolizines via Sequential Rhodium-Catalyzed [2+1]-Cyclopropanation, Palladium-Catalyzed Ring Expansion, and Oxidation Reactions from Pyridotriazoles and 1,3-Dienes

摘要

An efficient, one-pot synthetic method for producing functionalized indolizine derivatives was developed via a Rh-catalyzed [2 + 1]-cyclopropanation, Pd-catalyzed ring expansion, and subsequent Oxidation using manganese dioxide from pridotriazoles and 1,3-dienes.
