摘要：
Various indoles and carbazoles were synthesized from o-alkenyl anilines and o-aryl anilines by the beta-C(sp(2))-H bond amination cyclization without any oxidants or hydrogen acceptors. Likewise, employing o-alkyl anilines as substrates, indole products are also obtained by the beta-C(sp(3))-H bond amination cyclization, and dehydrogenation. In this cross-dehydrogenative coupling, many different functional groups are tolerated, and hydrogen gas is the only by-product, thereby providing an intrinsically waste-free approach for the synthesis of indoles and carbazoles.
