A concise and flexible method, based upon the kinetic
 resolution of racemic α-furfuryl amine derivatives, for the
 asymmetric synthesis of 1-deoxy-azasugars is described.
 (-)-1-Deoxymannojirimycin 1a has been synthesized in nine
 steps (5.8% overall yield) from the α-furfurylamine
 derivative 3 and its enantiomer (+)-1-deoxymannojirimycin 1b has
 been similarly synthesized in nine steps (3.7% overall yield)
 from (S)-3. (-)- and (+)-1-Deoxyaltronojirimycin,
 16a and 16b, have also been synthesized in five steps (overall
 yields 21.5% and 25.4%, respectively) from the intermediates 9a
 and 9b, respectively.
