Practical synthesis and electronic study of non-spiro and spiropyrano[2,3-c]pyrazole-3-carboxylate derivatives via uncatalyzed domino one-pot, four-component reactions
A practical and efficient synthesis of non-spiro and spiropyrano[2,3-c]pyrazole-3-carboxylate derivatives was developed. The synthesis was achieved via a domino one-pot, four-component reaction of diethyl oxaloacetate, hydrazine, aldehyde and malanonitrile in refluxing acidic ethanolic solution unde...
