Abstract
The enantiomeric resolution of five substituted 2-(4-pyridylalkyl)-1-tetralone derivatives has been achieved on three macrocyclic glycopeptide antibiotic chiral stationary phases namely, Chirobiotic R, T, and V columns. The mobile phase used was hexane-ethanol-triethylamine (12:8:0.01, v/v/v). The flow rates were 1 mL/min for Chirobiotic T and 2 mL/min for Chirobiotic R and V respectively. The UV detection was carried out at 254 nm. The values of alpha of the resolved enantiomers of the reported tetralone derivatives were in the range of 1.32 to 2.51 on Chirobiotic R, 2.02 to 2.88 on Chirobiotic T and 1.55 to 2.54 on Chirobiotic V respectively while the values of Rs were in the range of 1.00 to 2.50 on Chirobiotic R, 1.00 to 1.95 on Chirobiotic T and 1.00 to 1.60 on Chirobiotic V respectively. The best resolution was achieved on Chirobiotic R column.
