Use of the N-tosyl-activated aziridine 1,2-dideoxy-1,2-iminomannitol as a synthon for 1-deoxymannojirimycin analogues

Abstract 1-Amino-1-deoxy- d -glucitol was converted into the selectively protected title compound 4 , an N -tosyl-activated aziridine that readily underwent ring opening with various nucleophiles. Further deprotection of the 5,6-diol moiety followed by ring closure under Mitsunobu conditions afforded the corresponding 6-substituted analogues of 1-deoxymannojirimycin.
