NIS-mediated oxidative arene C(sp²)–H amidation toward 3,4-dihydro-2(1<i>H</i>)-quinolinone, phenanthridone, and <i>N</i>-fused spirolactam derivatives

Abstract

A new radical-mediated intramolecular arene C(sp2)-H amidation of 3-phenylpropanamides or [1,1'-biphenyl]-2-carboxamides was developed to prepare a series of 3,4-dihydro-2(1H)-quinolinone and phenanthridone derivatives in moderate to excellent yields (33-94%). Spirolactams could also be obtained using this protocol.
