modular method for the synthesis of (Z)-3-[amino(phenyl/methyl)methylidene]-1,3-dihydro-2H-indol-2-ones starting from easily available 3-bromooxindoles or (2-oxoindolin-3-yl)triflate and thioacetamides or thiobenzamides is described. A series of 49 compounds, several of which have previously been shown to possess significant tyrosin kinase inhibiting activity, was prepared in yields varying mostly from
一种高度模块化的方法,从易于获得的3-溴代吲哚或(2-氧代吲哚开始)合成(Z)-3- [氨基(苯基/甲基)亚甲基] -1,3-二氢-2 H-吲哚-2-酮描述了-3-基)三氟甲磺酸盐和硫代乙酰胺或硫代苯甲酰胺。制备了49种化合物,其中一些化合物先前已显示出具有显着的酪氨酸激酶抑制活性,其收率大多在70%至97%之间变化,并且始终超过通过其他已公开方法获得的产率。该方法包括Eschenmoser偶联反应,该反应是非常可行的(即使不使用除叔酰胺以外的亲硫基团)并且可扩展。所有产物的(Z)-构型通过NMR技术证实。
