5-Amino-N-(2,2-dialkoxyethyl)pyrazole-4-carboxamides obtained by hydrolytic cleavage of 5-(2,2-diethoxyethyl)pyrazolo[3,4-d]pyrimidin-4-ones or by condensation of 3-(dimethylamino)-N-(2,2-dimethoxyethyl)-2-cyanoacrylamides with alkylhydrazines in formic a

Synthesis of new di-, tetra-, and hexahydropyrazolo[3,4-e][1,4]diazepine derivatives

Alkaline hydrolysis of 5-(2,2-diethoxyethyl-, aroylmethyl-, or ethoxycarbonylmethyl)-1H-pyrazolo-[3,4-e]pyrimidin-4(5H)-ones gave 5-amino-N-(2,2-diethoxyethyl-, aroylmethyl-, or carboxymethyl)-1H-pyrazole-4- carboxamides which underwent cyclization to the
