  Diastereoselective addition of lower order vinylcuprates to (R)-2,3-O-Isopropylideneglyceraldehyde

  摘要：

  Highly syn or anti selective addition of lower order lithium vinylcuprates generated from alkenyl bromides 1 to (R)-2,3-O-isopropylideneglyceraldehyde (2) can be achieved, respectively, depending on the substitution pattern of the vinyl moiety and the solvent. Alpha-Trimethylsilyl substituted vinylcuprates possessing an alkyl substituent Z to copper react with excellent syn selectivity in ether whereas a highly anti selective addition is observed for cuprates bearing a hydrogen atom Z or alpha to the metal in THF. A model is proposed to rationalize these complementary selectivities.

  Synthesis of Imidazolo-Piperidinopentoses as Nagstatine Analogues

  摘要：

  The syntheses of the four imidazolo-piperidino-pentoses 3-6, which belong to the D-series, and of their L-enantiomers, ent-3 to ent-6, are reported. Ascorbic acid and isoascorbic acid were converted over several steps into the L-threo/L-erythro- and the D-erythro/D-threo-configured aldotetroses, respectively, which are the key building blocks for the eight target imidazolo-pentoses cited above. Nucleophilic addition of a metallated imidazole to any one of these four aldotetroses gave the corresponding two diastereomeric adducts, intramolecular cyclisation of which provided the expected bicyclic target molecules, with some protection and deprotection steps being unavoidable prerequisites. The structures and configurations of all eight piperidinoses in Scheme 1 were determined unambiguously, by a combination of H-1/C-13 NMR spectroscopy, circular dichroism (CD) and MD values, in conjunction with single-crystal X-ray diffraction analyses of the L-arabino and D-lyxo azasugars ent-3 and 6. Although lacking the hydroxymethylene group in the C(5) position, the overall structure of these eight stereomers strongly resembles that of the natural product nagstatine (1), a potent inhibitor of N-acetyl-beta -D-glucosaminidase. As a matter of fact, after examination of the inhibitory properties of these imidazolo-piperidinoses against six commonly encountered glycosidases, we observe that the L-arabino imidazolo-sugar ent-3 is a potent inhibitor in this series, with K-i = 1 muM both with a beta -glucosidase and with a beta -galactosidase. The D-ribo and D-xylo stereomers 4 and 5 proved to be inhibitors of a beta -glucosidase of similar magnitude (4: K-i = 20 muM; 5: K-i = 17 muM), the other stereomers being either modest to poor inhibitors, or showing no inhibition at all.

  Formaldehyde dialkylhydrazones smoothly add to sugar aldehydes without any need of promoter or catalyst. α-Hydroxy dialkylhydrazones, which are obtained in good yields and high stereoselectivities, have been successfully transformed in cyanohydrins by treatment with magnesium monoperoxyphtalate (MMPP) and in O-protected α-hydroxy aldehydes by ozonolysis or HCl mediated hydrolysis. No racemization was

  A new and efficient route to the synthesis of trialkoxy derivatives of D-erythrose (1) and D-threose from readily available D-glyceraldehyde acetonide was developed. The addition reaction of 1 with 1-(trimethylsilyl)vinyl cuprate reagent proceeded highly stereoselectively to afford anti addition product, which was then readily converted into allitol hexaacetate.

  DOI：10.1055/s-1992-34170

  日期：——

  All D-tetroses and D-pentoses having differentially protected hydroxy groups are synthesized by an iterative one-carbon chain-elongation cycle commencing with the addition of 2-(trimethylsilyl)thiazole to 2,3-O-isopropylidene-D-glyceraldehyde. One half of the resulting secondary alcohol is epimerized by an oxidation-reduction sequence. The aldehydes are revealed from the two diastereomeric alcohols by thiazole-to-formyl conversion.
