A selective oxidative fission of the heterocyclic nucleus of 5-methyl-2-(acylmethyl)furans or 2-(5-methyl-2-furyl)-1,3-dicarbonylcompounds by m-chloroperbenzoic acid allows the easy synthesis of the 3(2H)-furanone system.
A very efficient photo-sensitized oxidation of 2-(2-furyl)-1,3-dicarbonyl compounds 1 afford directly hydroperoxides 2 in stereoselective way. Compounds 2, easily isolated, can be conveniently employed in a selective epoxidation of trisubstituted allylic alcohols by a Sharpless-type procedure.
