Cyclobutane malonoyl peroxide I, prepared in a single step from the com. available diacid 6, is an effective reagent for the dihydroxylation of alkenes. Reaction of a chloroform solution of I with an alkene in the presence of 1 equiv of water at 40 °C followed by alk. hydrolysis leads to the corresponding diol, e.g., II, in 30-84% yield. With 1,2-disubstituted alkenes, the reaction proceeds with syn-selectivity (3:1 → 50:1). A mechanism consistent with exptl. findings is proposed, which is supported by deuterium and oxygen labeling studies and explains the stereoselectivity observed Alternative reaction pathways that are dependent on the structure of the starting alkene are also described leading to the synthesis of allylic alcs. and γ-lactones.
