A new one-pot three-component synthesis of 2,4-diamino-5H-chromeno[2,3-b]pyridine-3-carbonitrile derivatives.
In this study, a three-component one-pot synthesis of new 2,4-diamino-5H-chromeno[2,3-b]pyridine-3-carbonitriles derived from 2-amino-1,1,3-tricyanopropene, salicylic aldehydes and secondary cyclic amines is reported. The reaction is conducted in ethanol at ambient temperature in good-to-excellent yields.
