A Catalyst-Free, One-Pot, Three-Component Approach for the Synthesis of 2-[1-Aryl-2-(azaaryl)ethyl]malononitriles via sp3 C–H Activation of 2-Methyl Azaarenes
Combinatorial libraries of 2-[1-aryl-2-(azaaryl)ethyl]malononitriles derivatives have been synthesized by catalyst-free, one-pot, three-component protocol and employing water as a solvent. Simple reaction, open air reaction, and easy isolation are added advantages of this method. The method is applicable for aryl as well as heteroaryl systems and provides a convenient access for the synthesis of novel quinoline
