A. Pecunioso et al., SYNTHESIS AND ENANTIOMERIC EXCESS DETERMINATION OF -6-(N-METHYL-N-BENZYLOXYCARBONYLAMINO)-CYCLOHEXENE, Tetrahedron : asymmetry, 8(5), 1997, pp. 775-778
The title compound was obtained with high regioisomeric and enantiomer
ic purity starting from the tartrate salt of (1S,2S)-1-hydroxy-2-methy
laminocyclohexane. The determination of the enantiomeric excess both o
f the title compound and of its precursor 2-(N-methyl-N-benzyloxycarbo
nylamino)cyclohexanone was determined by NMR experiments with chiral s
hift reagents. (C) 1997 Elsevier Science Ltd.
