  Synthesis of extended spacer-linked neooligodeoxysaccharides by metathesis olefination and evaluation of their RNA-binding properties

  摘要：

  The preparation of linear 1,4-butanediol-linked oligodeoxysugars 50-53, 58 and 60 is described which are potential binders to polynucleotides. Various aminodeoxymonosaccharides 9, 13-18, 30, 31 and 40-42 which are either allylated at the anomeric center or at C4 were subjected to the metathesis olefination protocol. Depending on the position of allylation E/Z-mixtures of C-2-symmetric head-to-head or tail-to-tail homodimers were formed. Among them, saccharides 13, 30, 31 and 40 were transformed into the corresponding 1,4-butanediol linked disaccharides 50-53 by catalytic hydrogenation of the central olefinic double bond and exhaustive deprotection. In order to target extended spacer-linked neooligosaccharides homodimeric aminoglycoside 37 was bisallylated and subjected to cross metathesis conditions using methyl 4-O-allyl daunosamide 40 as reaction partner which yielded two desired trimeric and tetrameric linearly spacer-linked daunosamine derivatives. After hydrogenation and deprotection two additional probes 58 and 60 for nucleic acid binding studies were at hand. (C) 2004 Elsevier Ltd. All rights reserved.

  Bi(OTf)3 promoted direct and highly stereoselective glycosylation of “disarmed” and “armed” glycals to synthesize 2-deoxyglycosides has been reported. The tunable and solvent-controlled chemoselective activation of deactivated glycal donors distinguishing the competitive Ferrier and 1,2-addition pathways was discovered to improve substrate scope. The practical versatility of the method has been amply

  The rearrangement of dihydropyrans and dihydrofurans featuring appending olefins has been studied. The rearranged products bear resemblance with polyunsaturated di- and trisaccharides. Examples of functionalization prior to, or following, rearrangement are provided suggesting that the method should be useful for the synthesis of nonclassical saccharides. This work also illustrates the power of cascade
