Metal-free intramolecular hydroarylation of alkynes
Organic Chemistry Frontiers(2022)
摘要
An efficient metal-free intramolecular hydroarylation reaction of alkynes is described here. A series of aryl and N-group attached alkynes generated the intramolecular hydroarylation products in high yields. In addition to that, less steric hindrance alkynes led to complex mixtures resulting from the formal oxidation and reduction of hydroarylation products. Furthermore, a one-pot synthesis of 4,4′-disubstituted-1,1′-binaphthyls is accomplished via a hydroarylation/oxidative coupling protocol.
