Synthesis of 1-deoxymannojirimycin analogues using N-tosyl and N-nosyl activated aziridines derived from 1-amino-1-deoxyglucitol

3,4;5,6-Diisopropylidene protected 1-amino-1-deoxy-D-glucitol was transformed into N-tosyl and N-nosyl activated aziridine intermediates, which underwent ring opening by reaction with various nucleophiles. The 5,6-diols resulting from selective hydrolysis of the terminal acetal group were subjected to (2-N→6-OH) cyclisation using two different methods for activation of 6-OH. Final deprotection of the N-nosyl and 3,4-acetal group proceeded smoothly to afford 6-substituted analogues of 1-deoxymannojirimycin.

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

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.
