Abstract

Today, the importance of radical reactions in organic synthesis has increased, since functional group conversion of organic compounds under mild conditions is critical for the preparation of natural products and fine chemicals. 1 Especially, radical cyclization reactions to carbon-carbon, carbon-oxygen, and carbon-nitrogen multi bonds through the 5-exo-and 6- exo-manners are the most powerful and versatile methods for the construction of cyclic ...
