Abstract

803: Tetrahedron 1985, 41, 2163. an endoperoxide 4, which either liberates carbon monoxide to afford &keto acid 2 or is attacked by solvent alcohol to produce a-hydroxyadipic acid monoester 3. Interestingly the product distribution has been found to be highly dependent upon the reaction temperature. The intermediacy of endoperoxide 4 has been discussed on the basis of products 2 and 3, as well as CO and C02 liberated.
