ALR1 range from 1 (in case of compound 3b) to 238 (in case of compound 3a). Finally, we found out that the presence of an additional (secondary) aromatic area is not a prerequisite feature for ARI activity.

obtained with the combination of CH3CN as the solvent and KI as the catalyst (Table 1, entry 6). All compounds were isolated by flash column chromatography, and the solids were further recrystallized. Structural identification was based on spectroscopic methods (IR, NMR and HRMS). The data show that the most selective procedure for C-a substitution is the one with CH3CN and KI. Thus, we went on to investigate
