The invention relates to a synthetic method of 3,4-dihydroisoquinolin-1-one and isoindolin-1-one derivatives; particularly, a base is added to 2-allyl-benzamide serving as a raw material under the protection of nitrogen, and heating is performed in a solvent to obtain dihydroisoquinolin-1-one or isoindolin-1-one compounds under high yield. The synthetic method is simple to perform, high in reaction yield and low in usage of bases in reaction, has no need for using transition metal catalysts, and is highly worthy of application in the industrial preparation of isoindolin-1-one compounds.

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)2PdCl2, CuI, and Et3N in DMF mostly at 80°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.
