Abstract

Cyclobutane malonoyl peroxide (7), prepared in a single step from the commercially available diacid 6, is an effective reagent for the dihydroxylation of alkenes. Reaction of a chloroform solution of 7 with an alkene in the presence of 1 equiv of water at 40° C followed by alkaline hydrolysis leads to the corresponding diol (30–84%). With 1, 2-disubstituted alkenes, the reaction proceeds with syn-selectivity (3: 1→ 50: 1). A mechanism consistent ...
