New pyrazolo[3,4-b]pyrazines: Synthesis and biological activity

Some new pyrazolo[3,4-b]pyrazines and related heterocycles were synthesized and evaluated for their antifungal and antiparasitic activities. The key intermediate, 6-amino-3-methyl-1-phenyl-1H-pyrazolo[3,4-b]pyrazine-5-carbonitrile (3) was obtained in a one-pot synthesis via the reaction of 5-amino-3-methyl-4-nitroso-1-phenylpyrazole 2 with malononitrile.
