The enantioselective synthesis of optically active (+)-tetraol 12, corresponding to the C9-C16 subunit of biogenetically and biologically intriguing oxasqualenoids 2-4, has been accomplished by the biomimetic and stereospecific cyclization of diepoxide 22. The experimental details for the preparation of the known meso tetraol 11, corresponding to the C9-C16 subunit of teurilene 1, are also described. (C) 2002 Elsevier Science Ltd. All rights reserved.
