      Direct separation of the enantiomers of (+/-)-metoprolol tartrate on impregnated TLC plates with D-(-)-tartaric acid asa chiral selector

      J. Planar Chromatogr. 18, 294-299 (2005). TLC of (+/-)-metoprolol tartrate and (-)-alprenolol tartrate on silica gel, with concentrating zone, on RP-18, on LiChrospher silica gel and on alumina, previously impregnated with the mobile phase (ethanol - water 7:3, containing D-(-)-tartaric acid as chiral selector). Detection under UV light at 254 nm and densitometric scanning at 230 nm. Direct separation of the enantiomers of (+/-)-metoprolol tartrate was achieved.

      Indirect resolution of enantiomers of penicillamine by TLC and HPLC using Marfey's reagent and its variants
      R. BHUSHAN*, H. BRÜCKNER, V. KUMAR (*Department of Chemistry, Indian Institute of Technology Roorkee, Roorkee 247 667, India)

      Bio. Chromatogr. 21(10), 1064-1068 (2008). Indirect chiral TLC separation of penicillamine (3,3-dimethylcysteine) enantiomers after derivatization with Marfey's reagent (FDNP-Ala-NH2) and two of its structural variants, FDNP-Phe-NH2 and FDNP-Val-NH2 on silica gel and RP-18 with phenol - water 3:1 and solvent combinations of acetonitrile and triethylamine phosphate buffer. The methods were applied for determination of the enantiomeric impurity of l-penicillamine, d-penicillamine, and pharmaceutical formulations of d-penicillamine.

      L-amino acids as chiral selectors for the enantioseparation of (±)-bupropion by ligand exchange thin-layer chromatography using Cu(II) complex via four different approaches
      S. BATRA, M. SINGH, R. BHUSHAN* (*Department of Chemistry, Indian Institute of
      Technology Roorkee, Roorkee – 247 667, India, rbushfcy54@gmail.com)

      J. Planar Chromatogr. 27, 367-371 (2014). TLC of (±)-bupropion on silica gel impregnated with 2 mM Cu(II) and 4 mM L-amino acid 1:2, with acetonitrile - methanol - chloroform 2:1:2. Detection by exposure to iodine vapors. The Cu(II) acetate–amino acid complex allowed efficient enantiomer separations. Four different approaches for impregnating/loading the ligand exchange reagent were evaluated. However, using a solution of Cu(II) acetate as mobile phase additive for the TLC plates impregnated with one of the L-amino acids allowed the best enantiomer separation.

      Enantiomeric resolution of N-methyl-a-amino acids by ligand-exchange chromatography
      H. BRUECKNER, (Inst. Food Technol., Univ. Hohenheim, D-7000 Stuttgart 70, FRG)

      Chromatographia 24, 725-738 (1987). TLC on chiral-plates with four solvent systems. Detection by spraying with 0. 1% ninhydrin in ethanol. Comparison of Rf values and resolution factors.

      Lactic acid enantiomers
      L. CECCHI, P. MALASPINA, (Cent. per la Studio Technol., Bromatol. e Microbiol. del Latte, CNR, Via Celoria 2, 20122 Milano, Italy)

      Anal. Biochem. 192, 219-221 (1991). TLC of D- and L-lactic acid enantiomers on Cu(II)-impregnated silica with dioxane - water 9:1. Confirmation of the separation by enzymatic tests. The separation is suitable for radiochemical measurements. The method is useful for rapid control of the radiochemical stability of both D- and L-forms of lactic acid.

      Thin layer chromatographic enantioseparation of miscellaneous compounds with bovine serum albumin in the eluent
      L. LEPRI, V. COAS, P.G. DESIDERI, L. PETTINI, (*Dept. of Public Health, Epidemiology, and Environm. Chem., Univ. of Florence, Via G. Capponi 9, 50121 Florence, Italy)

      J. Planar Chromatogr. 6, 100-104 (1993). The enantiomers of several optically active organic compounds have been separated using optimized chromatographic systems comprising RP-18 silica layers and eluents of different pH and ionic strength containing different amounts of bovine serum albumin (BSA) and organic modifier. A total of more than 75 racemates have been separated with planar chromatography using BSA in the mobile phase. The data obtained might serve as a guideline for chiral separations.
