  First Preparation of Spacer-Linked Cyclic Neooligoaminodeoxysaccharides

  摘要：

  The preparation of novel cyclic 1,4-butanediol-linked oligoaminodeoxysugars 3-5 and 7 is described which are potential binders to polynucleotides. Neooligosaccharides 3-5 are assembled by two consecutive metathesis protocols. In the first phase metathesis-mediated dimerization of an aminodeoxymonosaccharide which was either allylated at the anomeric center or at C4 led to E/Z mixtures of C-2-symmetric homodimers which were transformed into the corresponding 1,4-butanediol linked disaccharides by catalytic hydrogenation of the central olefinic double bond. Double O-allylation of the head-to-head dimer set the stage for macrocyclization by means of ring-closing metathesis. This ring-closing process was highly dependent of the configuration in the carbohydrate moieties. arabino-Configured homodimer 15 directly yielded the macrocycle 32 which contains two sugar units while under the same metathesis conditions the corresponding ribo-configured starting homodimer 19 afforded cyclic neotetra- and neohexasaccharides 34 and 35 after a preceding dimerization and trimerization step, respectively. In addition, homodimer 23 was coupled with silylglycoside 14a under Lewis-acid promoted glycosidation conditions to furnish the doubly glycosylated homodimer 31. Ring-closing metathesis afforded the macrocyclic neoaminodeoxyoligosaccharide 36 with alternating 1,4-butanediol linkage and glycosidic bond. The primary cyclization products were finally transformed into the respective cyclic neoaminodeoxyoligosaccharides 3-5 and 7 by catalytic hydrogenation and standard deprotection conditions.

  A Short and High Yield Access to Glycosyl Donors of Amino-Deoxy-Sugars of Biological Relevance

  摘要：

  Synthesis of silylglycosides of 3-azido-2-deoxy-L-arabino- and ribo-hexopyranoses 4 and 5 has been achieved in 3 steps and 44,6% and 18% overall yields, respectively. The corresponding N-trifluoroacetamido derivatives 9 and 10 were further prepared in 3 steps. Usefulness of 4, 9, and 10 was demonstrated by coupling with epipodophyllotoxin derivatives or with suitably protected aminoacids such as serine or 4-OH-phenylglycine or 4-OH-phenylglycinyl glucoside.

For an investigation of structure-activity relationships, the four diastereomeric amino sugars daunosamine, acosamine, ristosamine, and epi-daunosamine were synthesised in short and efficient routes starting from commercially available rhamnose. Several glycosyl donors were provided and their use was exemplified in the synthesis of acosaminyl-e
