The invention relates to tetra-substituted heteroarylic compounds of the formula (I) wherein X1, X3 and X4 are independently C or N, Y is C-H, N-H or N, wherein the total number of nitrogen atoms represented by X1, X3, X4 and Y is 1 or 2; rings A and B are independently selected from phenyl or pyridyl; R1, R4, R', R", n and m are as defined herein. Such compounds are suitable for the treatment of a disorder or disease which is mediated by the activity of MDM2 and/or MDM4, or variants thereof.

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
