Cyclopropyl carbinols la-e react with H2O2 in the presence of concd H2SO4 at 0-5 degrees C to furnish the corresponding hydroperoxides 2a-e in 45-82% yields. This efficient trapping of cyclopropylmethyl cations by the hydroperoxy group has been exploited to prepare compounds 14-23, a new series of cyclopropyl substituted beta-peroxy-lactones.
