One-pot synthesis constructs the pyrazolo[3,4-b]pyrrolo[3,4-d]pyridine-6-one skeleton using diverse substrates, highlighting its efficiency.
A one-pot synthesis of the pyrazolo[3,4- b ]pyrrolo[3,4- d ]pyridin-6-one skeleton has been developed using aryl methyl ketones, 3-aminopyrazoles, and enaminamides as substrates.
