The synthesis of new naphtho[1',2':5,6]pyrano[2,3-d]pyrimidines and related heterocycles has been reported. The key intermediate 3-amino-8-bromo-1-(p-methoxyphenyl)-1H-naphtho[2,1-b] pyran-2-carbonitrile (3c) was obtained in one pot synthesis by treating alpha-cyanocinnamonitrile (1c) with 6-bromo-2-naphthol (2). Antimicrobial activity was shown for some of the synthesized compounds.
已经报道了新的萘并[1',2':5,6]吡喃并[2,3-d]嘧啶和相关杂环的合成。通过处理α-氰基肉桂腈(1c)一次合成即可获得关键的中间体3-氨基-8-溴-1-(对甲氧基苯基)-1H-萘并[2,1-b]吡喃-2-腈(3c) )和6-溴-2-萘酚(2)。对某些合成化合物显示了抗菌活性。
