  Anionic Indole N-Carbamoyl N → C Translocation. A Directed remote Metalation Route to 2-Aryl- and 2-Heteroarylindoles. Synthesis of Benz[a]carbazoles and Indeno[1,2-b]indoles

  摘要：

  A new LDA-induced anionic N-C carbamoyl migration of 2-arylindoles (7) is reported. Treatment of N-carbamoylindoles 10 and 13, readily available by direct and ipso-borodesilylative Suzuki-Miyaura cross-coupling routes from 8 and 12, respectively, provides a general route to functionalized 2-arylindoles 11 and 14, respectively (Tables 1 and 2). The reaction has been applied to the synthesis of benzo[a]carbazoles 16 and indeno[1,2-b]indoles 18, and its intramolecularity has been established by a crossover experiment (Scheme 4).

  Nap-Phos, representing a new naphthyl-phenyl biaryl-type phosphine ligand class and available by a short synthesis (4 steps, 71% overall yield), effectively catalyzes the Suzuki-Miyaura (including highly hindered cases), hydrodehalogenation, and Heck reactions.

  Nap-Phos代表着一种新型萘基-苯基双芳基膦配体，可通过短合成路线（4步，总产率71%）制备，并能有效催化铃木-宫浦反应（包括高度受阻的情况）、氢去卤反应和赫克反应。

  scale, and were dramatically improved by the addition of a urea derivative catalyst. The introduced boryl group was converted to chloro, bromo, and phenyl groups without isolation of the borylated intermediate. Preliminary results indicated the importance of hydrogen bonding between the substrate and the urea additive.

  我们通过修饰联吡啶型配体的结构开发了铱催化的吲哚衍生物的2位选择性C–H硼氢化。甚至在克规模上，收率从好到坏不等，并且通过添加脲衍生物催化剂而大大提高了收率。引入的硼基被转化为氯，溴和苯基，而没有分离出硼化的中间体。初步结果表明，底物与尿素添加剂之间氢键的重要性。
