Determining the Synthesis of Pyrazoles via Multi-Component Reaction and Cyclization Cascade of Hydrazono Ugi Adducts

In organic synthesis, multicomponent reactions (MCR) and cascade reactions are frequently used. Different substituted pyrazoles are accessed using these two synthetic methods. In the first section, we’re interested in learning how to make aminocyanopyrazoles using a multicomponent process. The current study outlines a useful protocol for multicomponent reactions (MCRs)...
