CHIRAL DISCRIMINATION OF 1-PHENYLETHYLAMINE BY DIASTEREOMERIC SALT FORMATION WITH BILE-ACIDS - CRYSTAL-STRUCTURES OF CHOLIC-ACID SALTS WITH(R)-1-PHENYLETHYLAMINE AND (S)-1-PHENYLETHYLAMINE

Chiral discrimination of 1-phenylethylamine (1) by diastereomeric salt formation with bile acids is described. X-ray crystallographic studie s of the salts between cholic acid (2a) and (R)-, (S)-, and (RS)-1 rev eal that more densely packed (S)-1+2a salt crystallizes preferentially by treatment of 2a from racemic 1.
