A newsynthetic strategy for the enantioselective synthesis of members of the dolabellane family of marine natural products has been demonstrated for the specific examples beta-araneosene and isoedunol (1 and 2, respectively) by the pathway outlined in Scheme 1. Key steps include (1) diastereoselective alkylation of Seebach's chiral lactate acetal (6) by the iodide derived from 5; (2) Kulinkovich ethylenation
