As a part of systematic investigation of synthesis and biological activities of indole analogues linked to various heterocyclic systems, we have synthesized new compounds viz., 2-amino-4-(5′-substituted 2′-phenyl-1H-indol-3′-yl)-6-aryl-4H-pyran-3-carbonitriles (2a–i), 4,5-diamino-6-(5′-substituted 2′-phenyl-1H-indol-3′-yl)-8-aryl-2-oxo-2,6-dihydrodipyrano [2,3-b:3,2-e]pyridine-3-carbonitriles (3a–i)
作为对与各种杂环系统连接的吲哚类似物的合成和生物学活性进行系统研究的一部分,我们合成了新化合物,即2-氨基-4-(5'-取代的2'-苯基-1 H-吲哚-3 '-基)-6-芳基-4 H-吡喃-3-甲腈(2a – i),4,5-二氨基-6-(5'-取代的2'-苯基-1 H-吲哚-3'-基)-8-芳基-2-氧代-2,6-二氢二吡喃并[2,3- b:3,2 - e ]吡啶-3-甲腈(3a – i),4-氨基-5-(5'-取代2'-苯基-1 H-吲哚-3-基)-7-芳基-1 H-吡喃并[2,3- d ]嘧啶-2(5 H)-ones(4a – i),4-氨基-5-(5'-取代的2'-苯基-1 H-吲哚-3'-基)-7-芳基-1 H-吡喃并[2,3- d ]嘧啶-2 (5 H)-硫酮(5a – i),4-(5'-取代的2'-苯基-1 H-吲哚-3'-基)-6-芳基-1,4-二氢吡喃[2,3- c ]吡唑-3-胺(6a
