Tetrahedron-asymmetry | 2002

Stereospecific and biomimetic synthesis of CS and C2 symmetric 2,5-disubstituted tetrahydrofuran rings as central building blocks of biogenetically intriguing oxasqualenoids

Abstract 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.
