Separation of the enantiomers of some potassium channel activators using an alpha 1-acid glycoprotein column.

The separations of the enantiomers of some 3,4-dihydro-2,2'-dimethyl-2H-1-benzopyrans and a related tetrahydronaphthalene on alpha 1-acid glycoprotein (Chiral-AGP) are presented, together with the results from an investigation of the effects of organic modifier and pH on the separations achieved. The general utility of Chiral-AGP in separating the enantiomers of compounds from this class of antihypertensive agents is demonstrated in this paper.
