Galactose trichloroacetimidate

Unprotected galactose derivatives may be readily transformed into the trichloroacetimidates 8a-8g, as shown in Table VIII. Again, as demonstrated for the O-benzyl-protected compounds 8a, either the a-trichloroace-timidate 8a-a or the / -trichloroacetimidate 8a -/ may be obtained highly selectively, depending on the base used for the catalysis of the addition to the trichloroacetonitrile. [Pg.53]

Trichloroacetimidates may alo be used for the synthesis of 2-amino-2-deoxy-a-D-glycopyranosides particularly in the galactose series.36... [Pg.79]

Novel branched yS-CyDs with jS-o-galactose residues were chemically synthesized using the trichloroacetimidate method. Tetraacetyl galactosyl trichloroacetimidate was obtained with trichloacetonitrile in the presence of l,8-diazabicyclo[5.4.0] undec-7-ene (DBU) [101]. [Pg.39]
