The coupling reaction of carbon dioxide and terminal, internal, and highly substituted epoxides derived from renewable resources such as furfural, limonene, carvone, carvyl acetate, terpinen-4-ol, or ionone leads to the synthesis of new bioderived cyclic carbonates using an efficient aluminum catalyst under mild and solvent-free reaction conditions. Interestingly, the synthesis of highly substituted bioderived cyclic carbonates can occur with excellent diastereoselectivity, obtaining in some cases one diastereoisomer as the major product. The X-ray crystal structures of two enantiomerically pure carvone-based cyclic carbonates are reported.
