Catalytic transformation of carbon dioxide into seven-membered heterocycles and their domino transformation into bicyclic oxazolidinones by Wangyu Shi, Jordi Benet-Buchholz, Arjan W. Kleij

“…The synthetic application of these larger-ring cyclic carbonates is further demonstrated by showing their unique ability to serve as synthons for the preparation of bicyclic oxazolidinone pharmacores through an intramolecular domino sequence that involves a transient ketimine group, and various other intermolecular transformations. …”
