  been achieved using imines as reagents and potassium tert-butoxide as the catalyst. Depending on the solvent used, the reaction proceeds by two pathways. In THF, an addition/elimination reaction of exo-cyclic enol ethers with imines provides dihydroisobenzofuran derivatives in good yield. In DMSO, an addition/ring-opening/cyclization cascade reaction occurs with unexpected cleavage of C–O and C–C bonds

  for electrochemical radical cascade annulation of 1,2,3-benzotriazinones with alkynes is described. Under catalyst-free and external reductant-free electrolysis conditions, a range of isoquinolin-1(2H)-ones were obtained in moderate to good yields. Cyclic voltammetry and control studies suggest that the reaction proceeds via a radical pathway. Furthermore, this approach could be easily scaled up.

  Transition metal-free cascade reactions of alkynols with imines have been achieved using potassium tert-butoxide as catalyst. Switching the reaction solvent gives two kinds of products in good yield: isoquinolin-1(2H)-one derivatives and dihydroisobenzofuran derivatives. This approach was used to generate the natural product 8-oxypseudopalmatine in a two-step procedure from commercially available starting materials. Additionally, multicomponent reactions of alkynols, aldehydes, and amines were also successfully achieved to afford isoquinolin-1(2H)-one derivatives.

  An efficient method for the synthesis of substituted 1(2H)‐isoquinolone derivatives via nickel‐catalyzed annulation of substituted 2‐halobenzamidines with aryl alkynes in the presence of water is described. Benzo[4,5]imidazo[2,1‐a]isoquinolines were formed as the dominated products when dry dimethyl sulfoxide was used as the solvent. Furthermore, when benzyl substituted amidines were used as the substrates
