Copper-Catalyzed Selective Benzylic C–O Cyclization of <i>N</i>-<i>o</i>-Tolylbenzamides: Synthesis of 4<i>H</i>-3,1-Benzoxazines
A novel Selectfluor-mediated copper-catalyzed highly selective benzylic C–O cyclization for the synthesis 4H-3,1-benzoxazines is reported. The predominant selectivity for a benzylic C(sp3)–H over an aromatic C(sp2)–H bond in N-o-tolylbenzamides is achieved.
