A new approach to 1-deoxy-azasugars: Asymmetric synthesis of 1-deoxymannojirimycin and 1-deoxyaltronojirimycin

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.
