The Cu(OAc)2-catalyzed tandem reaction of 2-(1-alkynyl)benzaldimines with water for the synthesis of isoquinolin-1(2H)-ones was developed. Moreover, 4-halogen-substituted isoquinolin-1(2H)-ones were obtained in good yields simply by including N-halosuccinimides (NXS: X = Cl, Br, I) in the reaction system. Mechanistic studies indicated that the reactions are probably initiated by highly regioselective intramolecular cyclization of 2-(1-alkynyl)benzaldimines to give the corresponding isoquinolinium intermediates. The Cu(OAc)2-catalyzed tandem reaction of 2-(1-alkynyl)benzaldimines with water for the synthesis of isoquinolin-1(2H)-ones is developed. 4-Halogen-substituted isoquinolin-1(2H)-ones can be obtained in good yields simply by including N-halosuccinimides (NXS) in the reaction system. Mechanistic studies are also undertaken.

(Chemical Equation Presented) A variety of substituted isoindolin-1-ones are readily prepared in good to excellent yields under very mild reaction conditions by the reaction of o-(1-alkynyl)benzamides with ICl, I2, and NBS. In a few cases, subs

Novel palladium migration/arylation methodology for the synthesis of complex fused polycycles has been developed, in which one or more sequential Pd-catalyzed intramolecular migration processes involving C-H activation are employed. The chemistry works best with electron-rich aromatics, which is in agreement with the idea that these palladium-catalyzed C-H activation reactions parallel electrophilic aromatic substitution.
