                                    Desymmerization of symmetric FTY720 by substitution of different alkyl groups for one of the prochiral hydroxymethyl groups was performed. The size of the alkyl groups and the absolute configuration at quaternary carbon were important on immunosuppressive activity. (C) 1997 Elsevier Science Ltd. All rights reserved.
