摘要

Ozone-mediated cyclization of a series of unsaturated hydroperoxides 7, prepared from dienes 2, afforded the corresponding yingzhaosu A analogues 9 in moderate to high yield. X- Ray crystallographic analysis of two yingzhaosu A analogues, endo-9f and 13, showed that the 2, 3-dioxabicyclo [3.3. 1] nonane system adopts a chair–boat arrangement. Subsequent treatment of endoperoxides 9 with Ag2O/MeI afforded the expected methyldioxy- ...
