Abstract

A series of methoxy-substituted 2,2-di(4-methoxyphenyl)-2H-naphtho[1,2-b]pyrans has been synthesised from 3-alkoxycarbonyl-1-naphthols and 1,1-di(4-methoxyphenyl)prop-2-yn-1-ol. The influence of the methoxy group on the wavelength of maximum absorption and the stability of the ring-opened naphthopyrans is discussed.
