O- and S-Nucleophiles including galactose, serine and cysteine derivatives undergo MICHAEL-type additions to hex-1-en-3-uloses to furnish stereoselectivity the α-2-deoxy-ulosides. The keto function at C-3 can be reduced stereoselectively with NaBH4. Both configurations can be obtained depending on the presence or absence of CeCl3. Glycosylation takes place either base catalyzed with DBU (1,8-diazabicyclo[5.4.0]undec-7-ene) or KCN/18-crown-6 or acid catalyzed by ZnI2.
