Tada, Masahiro,Nieda, Yuuki
, p. 1416 - 1418 (1988)
Photochemical reaction of 3-substituted 2-cyclohexen-1-ones with methyl cyclohexene-1-carboxylate gave only head-to-tail, cis-transoid-cis photoadduct.The photoadducts of 3-methyl-2-cyclohexen-1-one with methyl-1-cyclopentene-1-carboxylate and with methyl 1-cyclobutene-1-carboxylate had head-to-head, cis-transoid-cis ring system.
