  Palladium-Catalysed Heteroannulation with Terminal Alkynes: a Highly Regio- and Stereoselective Synthesis of (Z)-3-Aryl(alkyl)idene Isoindolin-1-ones

  摘要：

  A highly regio- and stereoselective method for the synthesis of (Z)-3-aryl(alkyl)idene isoindolin-1-ones through palladium-copper catalysis is described. 2-Iodobenzamide 1 and its substituted derivatives 2-10 were reacted with terminal alkynes 11-19 in the presence of (PPh3)(2)PdCl2, CuI, and Et3N in DMF mostly at 80 degrees C for 16 h to yield the 2-alkynyl substituted benzamides 20-38, 40-45, 77 which could then be cyclised with NaOEt in EtOH to the 3-aryl(alkyl)idene isoindolin-1-ones 46-49, 51, 53-55, 57, 59-71, 73 and 75. In certain cases, the isoindolin-1-ones 50, 52, 56 and 58 could be directly obtained by the palladium-catalysed reactions. (C) 2000 Elsevier Science Ltd. All rights reserved.

  o-Iodobenzamide or its N-substituted derivatives 4-10 and terminal alkynes 11-17 reacted in DMF in the presence of bis(triphenylphosphine)palladium(II)chloride, cuprous iodide and triethylamine leading to (Z)-3-arylidene isoindolin-1-ones (22, 24, 27 and 28) or o-alkynyl N-substituted benzamides (I). The latter could be cyclised with sodium in ethanol in a completely regio and stereoselective manner to (Z)-3-aryl(alkyl)idene isoindolin-1-ones 18-35.

  o-碘苯甲酰胺或其N-取代衍生物4-10与末端炔烃11-17在二甲基甲酰胺中，在双(三苯基膦)二氯化钯、碘化亚铜和三乙胺的存在下反应，得到（Z）-3-芳基亚甲基异吲哚啉-1-酮（22, 24, 27 和 28）或o-炔基N-取代苯甲酰胺（I）。后者可在乙醇中与钠完全区域和立体选择性环化为（Z）-3-芳基（烷基）亚甲基异吲哚啉-1-酮18-35。
