An Organocatalyzed Multicomponent Reaction: A Rapid and Efficient Practical Approach for 4H‐pyrano[3,2‐c]quinoline‐3‐carbonitriles Synthesis

A three‐component multicomponent approach has been developed at room temperature for the synthesis of 4H‐pyrano[3,2‐c]quinoline‐3‐carbonitriles. The all synthesized products were afforded in short reaction time with excellent yield using BABCO catalyst. The process is proficient with good tolerance of functional groups and well‐explored substrate scope. A three‐component multicomponent approach has been developed at room temperature for the synthesis of 4H‐pyrano[3,2‐c]quinoline‐3‐carbonitriles. The excellent yields of all synthesized products were afforded using methanol as reaction medium in short reaction time using DABCO catalyst. The substrate scope explored well and the process is proficient with good tolerance of functional groups.
