摘要：
A facile stereoselective synthesis of a constituent of antimycin A1 and also the new virginiamycin inducing factor, NFX-2((-)-1) has been achieved. (2RS, 3RS, 4SR)-2-Hexyl-3-hydroxy-4-pentanolide((+/-)-1) was obtained by stereoselective intramolecular aldol condensation of 2-(2-bromooctanoyloxy)-1-propanal (7) as the key reaction. (+/-)-1 was kinetically resolved by asymmetric esterification with a lipase, affording optically pure (-)-1 and its enantiomer (+)-1.
