- A multicomponent reaction has been developed for the synthesis of polyfunctional pyrazole derivatives from readily available arylglyoxal monohydrates, tosylhydrazine, and aldehydes or ketones. This synthetic method has significant advantages in broad substrate scope, excellent regioselectivity, and simple operation.
