실험 절차

To a stirred solution of propyl (7-azido-4-fluoro-6,7,8,9-tetrahydropyrido[1,2-α]indol-10-yl)acetate (1 eq) and prop-2-yn-1-ylbenzene (1.5 eq) in benzene (0.3M) at room temperature was added chloro(1,5-cyclooctadiene) (pentamethylcyclopentadienyl)-ruthenium(II) (0.1 eq). The reaction mixture was flushed with nitrogen then aged at 80° C. for overnight, cooled to room temperature, filtered through silica gel, washed with EtOAc and concentrated. The residue was purified by column chromatography on silica gel eluting with EtOAc/Hexane (0 to 50%) to give the desired material as a brown oil. The racemic mixture was resolved by HPLC using a 50×400 mm Chiralpak AD column eluting with 15% MeOH, 15% EtOH, 69.75% Hexanes and 0.25% Et3N at 50 mL/min and 254 nm to afford the desired chiral ester with retention time of 9.6 and 11.6 min respectively.
