Reactions of Chloroethynylphosphonates with 2-Aminoquinoline and 1-Aminoisoquinoline
The reactions of chloroethynylphosphonates with 2-aminoquinoline and 1-aminoisoquinoline proceeded chemoand regioselectively to form the original fused tricyclic compounds with pharmacophore groups, namely dialkyl (imidazo[1,2- a ]quinolin-2-yl)- and (imidazo[2,1- a ]isoquinolin-2-yl)phosphonates in high yield.
