Article abstract of DOI:10.1515/HC.2005.11.2.139

A variety of naphtopyrans 1 has been prepared by reaction of 2-naphtol with aryl (or alkyl) idenemalononitriles. The reaction of the naphtopyrans with triethylorthoformiate and then with primary amines and hydroxylamine, leads to new naphtopyrano [2, 3-d] pyrimidines 3 and 4, whose structures were confirmed by IR and NMR spectroscopy.
