K. Mizuno et al., A NOVEL INTRAMOLECULAR PHOTOCYCLIZATION OF METHYL ETHYLBUT-2-ENYLOXYMETHYL)NAPHTHALENE-1-CARBOXYLATE VIA 1,9-HYDROGEN ABSTRACTION, Chemical communications, (16), 1998, pp. 1659-1660
Irradiation of a benzene solution containing methyl ethylbut-2-enyloxy
methyl)naphthalene-1-carboxylate 1 gave an eight-membered keto ether 2
as the main product via a novel 1,9-hydrogen abstraction of the ester
