Synthesis of 5-Phenylnaphthobenzofuran by Ambident Alkylation of 1-Naphthol

Reaction of 1-naphthol with 2-chlorocyclohexanone in alkaline alcohol gave as the major product 5-(2'-oxocyclohexyl)-7,8,9,10-tetrahydronaphthobenzofuran (1), which could be converted to the title compound 5 by reduction and dehydrogenation.This product arises from ambident alkylation of 1-naphthol at the 2- and 4-positions.Via the 2'-oxocyclohexyl ether, 5 was also synthesized from 4-phenyl-1-naphthol.
