Cyclophellitol has been synthesized from 5,6-enoglucoside efficiently. The carbacyclic skeleton was constructed through a Ferrier reaction mediated by PdCl2. The regioselectivity on the oxirane ring opening with Mes(2)BCH(2)Li at the key step is found to be controlled by the hydroxy protecting group. (C) 1998 Elsevier Science Ltd. All rights reserved.
