Stereochemistry of metabolism of amphetamines: use of (-)-alpha-methoxy-alpha-(trifluoromethyl)phenylacetyl chloride for GLC resolution of chiral amines.

J Gal

Journal of pharmaceutical sciences, 66(2), 169-172 (1977-02-01)

Amphetamine and eight related compounds were reacted with the chiral acylating reagent (-)-alpha-methoxy-alpha-(trifluoromethyl)phenylacetyl chloride to obtain, in each case, two diastereomeric amide derivatives. GLC conditions were found for the separation of the diastereomers in seven of the nine cases studied.
