the synthesis of new 2‐amino‐3‐cyano/alkoxycarbonyl‐8H‐thieno[2,3‐b]indoles 5 and another one for the synthesis of 2‐N,N‐dialkylamino‐3‐cyano/aryl‐8H‐thieno[2,3‐b]indoles 16, based either on acetylindoxyl 1 and (1‐acetyl‐1H‐indol‐3‐yl)malononitrile/cyanoacetates 14 or 2‐bromoacetylindoxyl 2 transformations. A new, simple, rapid, and efficient method for the synthesis of valuable key intermediate ma
我们报告了两种合成新的2-氨基-3-氰基/烷氧基羰基-8H-噻吩并[2,3 - b]吲哚5的方法,另一种用于合成2 - N,N-二烷基氨基-3-氰基的方法。 / aryl-8H-thieno [2,3-b]吲哚16,基于乙酰吲哚基1和(1-乙酰基-1H-吲哚-3-基)丙二腈/氰基乙酸酯14或2-溴乙酰基吲哚基2转化。一种新的,简单,快速而有效的方法,用于合成基于乙酰吲哚酚1的重要关键中间体丙二腈/氰基乙酸酯14已经开发了在三乙胺存在下与丙二腈或氰基乙酸酯缩合的方法。许多用于硫代乙酰胺的制备合成步骤6,1- acetylthioisatin 8,和2,2-二取代的indoxyls 13噻吩并[2,3-B]吲哚的合成过程中已被详细阐述。硫代乙酰胺6已被证明是对结核分枝杆菌H 37 Rv有活性的新型药物,其抑制浓度范围在5至21μg/ mL之间。
