Abstract:
The compatibility of the generation of furylhydroperoxides by a radical chain process with the presence of oxygen acceptors and transition metal catalysts allows the achievement of a modified Sharpless procedure for the epoxidation of allylic alcohols and oxidation of sulphides to sulphoxides. © 1992.

- This inversion of diastereoselectivity was observed in a more evident way by direct epoxidation of trans-3-penten-2-ol with furylhydroperoxide2a (R1 = -Me, R2 = -OEt, R3 = -Me) in presence of Ti(-OiPr)4 in dichloromethane solution at −17 °C for 17h: in fact the resulting epoxyalcohol was isolated in 42% yield as 21/79 erythro/threo mixture
