  A concise access to 2-allenylindole derivatives based on the palladium catalyzed cross-coupling reaction of indolylborates

  摘要：

  The palladium catalyzed cross-coupling reaction of trialky](indol-2-yl)borates with prop-2-ynyl carbonates was developed for the preparation of 2-allenylindole derivatives. When the reaction of indolyl-borates with tert-prop-2-ynyl carbonates was carried out. 2-allenylindoles were obtained solely. Otherwise, indolylborates reacted with sec-prop-2-ynyl carbonates, giving rise to 2-allenylindoles and/or 3-(prop-2-ynyl)indoles depending on the catalyst used. (C) 1998 Elsevier Science Ltd.

  日期：——

  The influence of N-substituent of triethyl(indol-2-yl)borate (2) on the palladium catalyzed cross-coupling reaction was examined, and an efficiency of triethyl(1-tert-butoxycarbonylindol-2-yl)borate (2e) could be shown.
