Catalytic Domino Three-Component Synthesis of Functionalized Heterocycles from Carbon Dioxide

A catalytic domino process has been developed for larger-ring, functionalized cyclic carbonates with various types of functional groups and involves the intermediacy of a free-alcohol based six-membered cyclic carbonate. The domino protocol is propelled by a combination of an Al(III) complex and N-methyl-morpholine as supported by various control experiments.
