    • General reaction procedure for the synthesis of pyrrolo[2,1-a] isoquinolines: One mmol each of the isoquinoline (1a-b), phenacyl bromide/bromoacetic acid ester (2a-j), and chromone-3-carboxaldehyde (3a-c) derivatives were taken in a 100 ml RB flask. Then water (50 ml), CTAB (4 mmol) and DBU (1 mmol) were added and the mixture was stirred continuously for 1 h at room temperature. After completion of the reaction (monitored by TLC), the contents of the reaction mixture were poured into a separating funnel and extracted with ethyl acetate (3 × 25 ml). The organic layer was washed thoroughly with water until free from CTAB and base, dried over sodium sulfate, and evaporated to dryness in a rotary evaporator under reduced pressure. The residue was chromatographed over a column of silica gel (60-120 mesh) eluting with a mixture of hexane and ethyl acetate in different ratios, to yield the pyrrolo[2,1-a]isoquinolines (4a-x).
