Abstract :
A green and efficient one-pot, four-component synthesis of methyl 6-amino-5-cyano-4-aryl-2,4-dihydropyrano[2,3-c]pyrazole-3-carboxylates in water is described. The method is catalyst-free, atom-economical, and does not involve tedious work-up or purification affording the target compounds in good yields.
