DABCO catalyzed rapid one-pot synthesis of 1,4-dihydropyrano [2,3-c] pyrazole derivatives in aqueous media
A simple and efficient protocol is developed for the synthesis of dihydropyrano[2,3-c]pyrazole derivatives by a one pot, four component reaction of ethylacetoacetate, hydrazine hydrate, malanonitrile and various aldehydes in the presence of a catalytic amount of DABCO in aqueous medium. This method...
