The reaction of a series of monoterpenic olefins and Delta(4)-octalins with
dimethyldioxirane led to the corresponding epoxides in excellent yields. R
emarkable diastereoselectivity was observed for the Delta(4)-octalins. The
procedure consists simply in stirring the substrate, NaHCO3 and acetone, at
0 degrees C, with dropwise addition of an aqueous solution of oxone. (C) 2
