Indazoles as privileged scaffolds; synthetic strategies; clinical trial compounds; biological activities: anti-tubercular, antifungal, antibacterial, antileishmanial, anti-Parkinson's, anti-inflammatory, antidiabetic, and anticancer.
Herein, we report a t-BuONa-promoted method for the site-selective silylation of 2H-indazoles.
An electrochemical anodic oxidation approach was adopted to synthesize a variety of 1H-indazole derivatives in moderate to good yields.
A metal- and oxidant-free electrochemical synthesis of valuable indazoles was developed via the dehydrogenative C–N coupling of hydrazones.
This review systematically discusses all of the visible light-induced functionalization methodologies and mechanisms of two significant heterocycles, indazole and pyrazole.
