  A ZnBr2-mediated arylation of aryl/heteroaryl methyl bromides with arenes at 80 °C led to the formation of arylated products, which underwent subsequent 1,5-sigmatropic rearrangement followed by electrocyclization and aromatization with loss of a diethylmalonate unit to afford the corresponding annulated products.

  ]-fused carbazoles has been developed startingfrom suitably substituted 2/3-(bromomethyl)indoles and ar-enes under Lewis acid catalysis. The attractive feature ofthis protocol is the fact that a wide variety of π-conjugatedannulated carbazoles can be readily accessed by the appro-priate choice of arenes and heteroarenes. The annulationprotocol has been extended to (bromomethyl)benzene aswell as 2,

  在路易斯酸催化下，以适当取代的 2/3-（溴甲基）吲哚和芳烯为原料开发了]-稠合咔唑。本协议的有吸引力的特征是，可以通过竞争和杂种丁烯的应用选择可以容易地访问各种π缀合的咔唑。环化协议已扩展到（溴甲基）苯以及 2,5-双（溴甲基）噻吩。发现吲哚基-2-甲基乙酸酯的环化不如相应的2-(溴甲基)吲哚合适。然而，在苄体系的情况下，发现相应的醋酸盐更适用。在这项工作中开发的路易斯酸介导的级联环化序列可能会导致在多环芳香杂环领域的新应用。

  A ZnBr2-mediated arylation of N-protected 2/3-bromomethylindoles containing an electron-deficient malonylidene unit with arenes at 80 degrees C led to the formation of arylated products, which on Unprecedented 1,5-sigmatropic rearrangement followed by electrocyclization and subsequent aromatization with loss of diethylmalonate furnished the corresponding annulated carbazoles in reasonable yields.
