An expeditious synthesis of Z-3-alkylidene isoindolinones via combined palladium catalysed and friedel-crafts reactions
摘要:
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.
