A new synthesis of deoxynojirimycin (DNJ) analogues (galacto- and altrose c
onfiguration) has been achieved through a functionalized cyclopentene deriv
ative crafted from the norbornyl system, employing double reductive aminati
on as the key step. The new DNJ analogues have been evaluated against vario
us glycosidases and found to be moderate to strong inhibitors. (C) 2000 Els
