  On the preparative use of recombinant β(1–3)galactosyl-transferase

  摘要：

  A number of non-natural N-acyl derivatives of glucosamine is incubated with a recombinant beta(1-3)galactosyl-transferase and UDP-galactose. Surprisingly, the enzyme recognizes the non-natural accepters as substrates and transfers galactose onto the 3-OH group in a beta-mode to give a series of Lewis(c)-(type 1) disaccharides.

  An operationally simple protocol for diazotransfer on amine-containing carbohydrates has been developed. This high-yielding reaction can be conducted under ambient conditions. Reaction completion is indicated by the colour change of the Cu(II) catalyst. The utility of this protocol in chemical glycosylation has been demonstrated through the preparation of azide-containing glycosyl donors with orthogonal

  DOI：10.1016/s0008-6215(97)00071-2

  日期：1997.5

  Novel bola-amphiphilic compounds have been synthesised with D-glucose or D-galactose moieties as polar head groups. The sugar groups are coupled to the hydrophobic bridge, a chain of ten or twelve methylene groups, by an amide function at the C-2 site (2-alkylamido-2-deoxy-D-glucose derivative) or a glycuronamido function at the C-6 site. The former series is glycosylated with a cinnamyl group and the latter with octyl or decyl groups to afford pseudo macrocyclic compounds. (C) 1997 Elsevier Science Ltd.
