摘要

The synthesis of epoxides 2 by epoxidation of flavones 1 with isolated dimethyldioxirane (as acetone solution) at subambient temperatures is reported. These labile epoxides were isolated and completely characterized by UV, IR,'H and I3C NMR, MS, and C, H analyses. Warming to room temperature led to rearrangement to afford quantitatively the 3- hydroxyflavones Sb, h, i, n. Treatment of the epoxides 2b, f with methanol led to the 3- ...
