摘要: This invention relates to a method for separating enantiomers of a substituted 2-trifluoromethyl-2H-chromene-3-carboxylic acid or ester, a substituted 2-trifluoromethyl-1,2-dihydro-quinoline-3-carboxylic acid or ester, a substituted 2-trifluoromethyl-2H-thiochromene-3-carboxylic acid or ester, a substituted 3-trifluoromethyl-3,4-dihydro-naphthalene-2-carboxylic acid or ester, or a pharmaceutically acceptable salt of the acids or esters, using enantioselective fractional crystallization, enantioselective high performance liquid chromatography, enantioselective steady state recycling chromatography, or enantioselective multicolumn chromatography.
