synthesized via consecutive one-pot Suzuki–Miyaura and Knoevenagel reactions in water/ethanol mixture between imidazo[1,2-a]pyridine-2-carbaldehydes, arylboronic acids and malononitrile, methyl cyanoacetate or ethyl cyanoacetate. This environmental friendly procedure tolerates a wide range of boronic acids and affords a new substituted imidazo[1,2-a]pyridinyl propenenitriles in good yields under microwave
摘要 通过咪唑并[1,2-a]吡啶-2-甲醛、芳基硼酸和丙二腈在水/乙醇混合物中的连续单锅Suzuki-Miyaura和Knoevenagel反应合成了一系列咪唑并[1,2-a]吡啶基丙烯腈。 、氰基乙酸甲酯或氰基乙酸乙酯。这种环境友好的方法可以耐受广泛的硼酸,并在微波辐射下以良好的产率提供新的取代咪唑并 [1,2-a] 吡啶基丙烯腈。图形概要
