The chiral transformation of the optically active amine 10 to the corresponding alcohol 2 with opposite configuration is reported. The transformation is carried out via an S(N)2 type reaction of the N,N-ditosylimide, -NTs(2), by nucleophilic attack of the hydroxide, acetate or benzoate ion to give an inversion degree of 85-100%. 0-34% stereoselectivity was obtained in the corresponding chloride nucleophilic substitutions. Separation parameters for the chromatographic enantioseparations of the amines 10-12, the chlorides 4, 7, 9 and the alcohol 2 using a chemically bonded cyclodextrin GLC column are discussed.
