摘要

Enantioselective transformation of allyl carbonates into branched allyl carbamates by using amines and recycling CO_2 in the presence of an Ir complex and K3PO4 was accomplished. This provided branched allyl carbamates in fair to excellent yields with up to 98:2 regioselectivity and 93% ee. The role of CO_2 in this transformation is discussed as well.
