Popis: | The lead tetraacetate oxidation of (Z)-5, 10-secocholest-1(10)-ene-3β,5α−diol 3-acetate (1) gave products arising from: (i) conversion of the 5α−hydroxy group to the ketone function (2), (ii) intramolecular cyclization (to the 2α,5α−tetrahydrofurane-type ether 3), and (iii) allylic acetoxylation at the C(9) position (3 and 4), while similar oxidation of (E)-5, 10-secocholest-1 (10)-ene-3β,5α−diol 3-acetate (5) afforded mainly the product formed by conversion of 5α−OH to the keto-carbonyl group (6). |
