(±)-15-Deoxyspergualin is a new promising immunosuppressive agent, recently marketed in Japan for the control of cortico-resistant acute renal graft rejection. We describe here a nine-step synthesis starting from 7-bromoheptanenitrile and N1,N4-bis(benzyloxycarbonyl)spermidine, suitable for the production of multigram quantities of this unstable highly polar compound with an 18% overall yield. Furthermore, it opens the way for the synthesis of α-hydroxyglycine analogues.
(-)-15-Deoxyspergualin: A new and efficient enantioselective synthesis which allows the definitive assignment of the absolute configuration

(±)-15-Deoxyspergualin (DSG) has recently been marketed in Japan for the control of corticoresistant acute renal graft rejection. A nine-step total synthesis of its eutomer ((-)-DSG) 2 has been developed starting from 7-bromoheptanenitrile 3 and N1,N4-bis(benzyloxycarbonyl)spermidine. The use of a chiral α-alkylbenzyl group to protect the hydroxyl of the α- hydroxyglycine moiety allowed its chromatographic resolution and afforded a practical access to 2 with a high optical purity and a 7% overall yield. Moreover, X-ray structure analysis of the key crystalline intermediate 7b definitely confirmed the previously proposed absolute configuration of 2.
