Condensation of α-cyanocinnamonitriles with 6-bromo-2-naphthol: Synthesis of pyrano [2,3- d ]pyrimidine and pyrano[3,2- e ] [1,2,4]triazolo[2,3- c ]pyrimidine derivatives †
Naphthopyrans are synthesized by the reaction of cinnamonitriles with 6-bromo-2-naphthol; polysubstituted naph-thopyrimidines and naphthopyranotriazolopyrimidines are also prepared.
