摘要

Abstract Hydrogen peroxide/MoO 3, as an efficient and clean oxidizing system was used to afford diasteroselective oxidative cyclization of bisnaphthols to spirans in ethanol at 60° C with high yields. Bisnaphthols were prepared by the reaction of a series of aldehydes and 2- naphthol in the presence of a catalytic amount of H 3 [P (Mo 3 O 10) 4]. nH 2 O (HPa) in refluxing dichloromethane.
