  New 3-vinylation products of indole and investigation of its Diels–Alder reactivity: synthesis of unusual Morita–Baylis–Hillman-type products

  摘要：

  3-Vinylindoles as precursors of carbazole and bis-indole derivatives were synthesized. Then, to form new carbazoles, Diels-Alder reactivity of these vinylindoles was studied with various dienophiles. During the cycloaddition reaction, unusual Morita-Baylis-Hillman-type products were observed. The structure and the formation mechanism of the products is discussed. (C) 2010 Elsevier Ltd.

  分子内类固醇插入：吡咯基和吲哚基羧酸衍生的α-重氮酮与乙酸铑（II）的反应

  摘要：

  制备了由吡咯基和吲哚基羧酸衍生的α-重氮酮，并研究了其Rh 2（OAc）4催化的分解化学。这些反应通常导致酮类化合物对杂芳族系统进行烷基化，在某些情况下，该系统进行了CH或NH插入。提供了其中一些反应通过环丙烷中间体进行的证据。所描述的方法提供了易于接近稠合的吡咯基-或吲哚基-环烷酮体系的方法，其中羰基为杂芳族系统的β。
