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