Cascade Synthesis of Functionalized 2<i>H</i>‐Imidazo[5,1‐<i>a</i>]isoquinolinium Chlorides from Isoquinoline, Chloroformamidines (=Carbamimidoyl Chlorides), and Isocyanides

Abstract

Abstract Stable derivatives of 2 H ‐imidazo[5,1‐ a ]isoquinolinium chloride are obtained in good yields from the cascade reaction between isoquinoline, chloroformamidines (=carbamimidoyl chlorides), and isocyanides in dry MeCN ( Scheme 1 ).
