An efficient and green synthesis of novel highly functionalized nitrogen-fused pyrido[2′,3′:3,4]pyrazolo[1,5-a]pyrimidine derivatives using recyclable choline hydroxide

Choline hydroxide (ChOH) has been found to be a green and efficient basic ionic liquid catalyst for the synthesis of highly functionalized pyrido[2′,3′:3,4]pyrazolo[1,5- a ]pyrimidine derivatives through the reaction of a series of α,β -unsaturated ketones with 1 H -pyrazolo[3,4- b ]pyridin-3-amine...
