An efficient, catalyst-free methodology has been developed for the Michael addition reaction between d -glucosamine derivatives and various Michael acceptors. All reactions proceeded smoothly at room temperature to furnish novel sugar-derived vinylogous carbamates in high chemical yields and excellent stereoselectivity.
