dc.title	Epoxidation of Flavones by Dimethyldioxirane	en
heal.abstract	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-hydroxy-2-methoxyflavanone4s b,f as a mixture of cis and trans isomers.	en
