Peroxide-mediated site-specific C-H methylation of imidazo[1,2-: A] pyridines and quinoxalin-2(1 H)-ones under metal-free conditions

An effective approach to realize the direct methylation of imidazo[1,2-a]pyridines and quinoxalin-2(1H)-ones with peroxides under metal-free conditions is described. In this protocol, peroxides serve as both the radical initiator and methyl source. Methylated imidazopyridines and quinoxalin-2(1H)-ones were smoothly synthesized in moderate to good yields. A free radical reaction mechanism was proposed to describe the methylation process.

Visible-Light-Induced Alkoxylation of Quinoxalin-2(1H)-ones with Alcohols for the Synthesis of Heteroaryl Ethers

A direct and simple strategy to heteroaryl ethers via a visible-light-induced alkoxylation of quinoxalin-2(1H)-ones with alcohols under ambient conditions was developed. The commercially available, low cost alcohols served as alkoxylation reagents and solvents. This reaction has advantages of novel protocol, mild conditions, good functional-group tolerance, and high yields of products. (Figure presented.).
