activities. New ceramide analogues with an allene group in the sphingoid backbone were synthesized. The synthesis of the key intermediates involved the LiAlH4 reduction of oxazolidine intermediates via a directed reduction-elimination reaction. Hydrolysis of the oxazolidine, liberation of the amino group, and N-acylation provided new ceramide analogues. These new analogues may provide new resources to
