  Morita–Baylis–Hillman reaction of indole-2-carboxaldehyde: new vistas for indole-annulated systems

  摘要：

  DABCO-mediated Morita-Baylis-Hillman reactions of several 1-substituted-indole-2-carboxaldehydes are disclosed. It was discovered that carboethoxy or tert-butoxycarbonyl groups installed at N-1 undergo cleavage under the reaction conditions to afford 2-substituted indoles. Utility of the N-substituted adducts for preparing a variety of annulated indoles has been exemplified. (C) 2010 Elsevier Ltd. All rights reserved.

  Derivatives of indole-3-carbaldehyde oxime have been prepared that bear a carbon-carbon double bond at C-2 and a five- or six-membered ring linking the alpha-carbon artom of the vinyl group and the indole nitrogen atom. Compound 9, with a five-membered ring linking the two atoms, failed to undergo a cyclisation reaction on heating. However the oximes 16 and 22, with a six-memberd ring linking the two atoms. cyclised in boiling toluene. The cyclisation led to the formation of the pyrido-indoles 17 and 18, respectively.
