Stereoselective syntheses of 4-amino-aldoses, and chiral pyrrolidine derivatives from glycosylenamines

The stereocontrolled synthesis of N-protected 4-amino-4-deoxy-D-galacto and -L-arabino-pyranoses starting from glycosylenamines via aza- anhydropyranoses is described. The steroselective transformation of the intermediate aza-anhydropyranoses into chiral pyrrolidines is also reported.
