  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.

  The palladium-catalysed reactions of 2-iodobenzamides 1–5 with trimethylsilyl acetylene 6 led to 2-(2-trimethylsilyl)ethynyl benzamides 7–11 in excellent yields. The 2-(2-trimethylsilyl)ethynyl benzamides 7–11 underwent Friedel-Crafts reactions with acid chlorides 12–17 or anhydride 18 smoothly under mild conditions yielding the 3-alkylidene isoindolin-1-ones 19–38.

  N-Aryl(or, alkyl)-2-iodobenzamides underwent palladium-catalysed reaction with (trimethylsilyl)acetylene to form N-substituted-2-(trimethylsilyl)ethynyl benzamides, which on further Friedel-Crafts acylation and cyclisation yielded Z-3-alkylidene isoindolin-1-ones in a completely regio-and stereoselective manner.

  A domino sulfonylation/intramolecular C–N coupling/dehydrogenation reaction was realized between pent-4-ynamides and sulfonyl chlorides by catalysis of Cu(acac)2 and 2,2′-bis(diphenylphosphanyl)-1,1′-binaphthalene. The reaction provides a convenient approach to sulfonyl-functionalized pyrrol-2-ones. This method can also be applied to the synthesis of 3-alkylidene isoindolinones from 2-ethynyl-benzamides
