N-Allyl protected 3-O-benzyloxglutarimide 11 was synthesized as a useful variant of the chiral building block 10. This modification allowed a high-yielding deprotection of the allyl group from the lactam intermediate 14. Starting from this building block, the asymmetric syntheses of aza-sugars 6-deoxyfagomine (2), D-rhamnono-1,5-lactam (6), as well as D-deoxyrhamnojirimycin (5) have been achieved in high regio- and/or diastereo-controlled manner.
