A novel method for the preparation of 5,6-dihydropyrazolo[5,1-a]isoquinoline via indium(III)-promoted halocyclizations of N-propargylic sulfonylhydrazones has been developed. The pyrazole and 3,4-dihydroisoquinoline moieties were synchronously formed via
A direct anionic cyclization of 2-alkynylbenzonitrile to 3- substituted-1(2H)-isoquinolones and 3-benzylideneisoindol-2ones initiated by methoxide addition

Treatment of 2-(2-alkylethynyl)benzonitrile with sodium methoxide in refluxing methanol for 12 h gave 3-alkyl-1(2H)- isoquinolone in modest yield. Under the same reaction conditions, methanolysis of 2-(2-arylethynyl)benzonitrile lead to the formation of 3
