The synthesis of new [1]benzopyrano[3',4':5,6]pyrano[2,3-d]pyrimidines and related heterocycles has been reported. The key intermediate 2-amino-3-cyano-4-methyl-4H,5H-pyrano[3,2-c][1]benzopyran-5-one (3) was obtained in one pot synthesis from the reaction of 4-hydroxycoumarin and acetaldehyde-malononitrile (2). The antimicrobial screening was performed for some of the synthesized compounds.
已经报道了新的[1]苯并吡喃并[3',4':5,6]吡喃并[2,3-d]嘧啶和相关杂环的合成。一锅合成法由4-的反应制得关键中间体2-氨基-3-氰基-4-甲基-4H,5H-吡喃并[3,2-c] [1]苯并吡喃-5-酮(3)羟基香豆素和乙醛-丙二腈(2)。对一些合成的化合物进行了抗菌筛选。
