A simple and effective method is proposed for the synthesis of 4,5-diphenyloxazolyl-substituted o-hydroxynaphthaldehydes. Photochromic spirobenzochromeneindolines containing a 4,5-diphenyl-oxazole group at position 5 of the benzochromene fragment were obtained. In the cyclic form the new (diphenyloxazolyl)-substituted spiropyrans exhibit luminescent properties.
