The Photo-induced Diels-Alder Reaction of 2-Cycloocten-1-one and 2-Cyclohepten-1-one

Abstract

Abstract trans-2-Cycloocten-1-one and trans-2-cyclohepten-1-one, which are supposed to be formed by the ultra-violet irradiation of cis-2-cycloocten-1-one and cis-2-cyclohepten-1-one, give Diels-Alder addition products with cyclopentadiene and isoprene.
