Photolysis of 3-triphenylmethyl-Δ2-isoxazolines: a new method for CC-double bond cleavage
Abstract
U.v. irradiation of triphenylmethyl-Δ2-isoxazolines, formed by 1,3-dipolar addition of triphenyl-acetonitrile oxide to olefins, results in the elimination of the Ph3C group and subsequent fragmentation of the heterocycle to give a carbonyl compound and a nitrile.
