intermediates (2). Subsequent cyclocondensation by 1-aminoisoquinoline at room temperature in the presence of sodium carbonate gave the corresponding imidazo[2,1 -a]isoquinoline derivatives (3) in good yields as shown in the Scheme. The 2,4-dinitrobenzenesulfonyloxy group located at the a position to a carbonylgroup represents an increasingly important entity in both mechanistic and synthetic organic chemistry
