摘要：

The 1-azabicyclo[2.2.1]heptan-3-exo-ol (2) was resolved by fractional crystallisation of its hydrogen tartrate salts. The enantiomers (+)- and (-)-2 were oxidised to the ketones (-)-4 and (+)-4, respectively (Scheme). CD spectroscopy suggested that (-)-4 possesses the (1R,4S)-configuration. This absolute configuration was confirmed by single-crystal X-ray diffraction of the derivative (+)-(1R,4R)-3-(1,3-dithian-2-ylidene)-1-azabicyclo[2.2.1]-heptane ((+)-5).
