  Syntheses of TN building blocks Nα-(9-fluorenylmethoxycarbonyl)-O-(3,4,6-tri-O-acetyl-2-azido-2-deoxy-α-d-galactopyranosyl)-l-serine/l-threonine pentafluorophenyl esters: comparison of protocols and elucidation of side reactions

  摘要：

  T-N antigen building blocks N-alpha-(9-fluorenylmethoxycarbonyl)-O-(3,4,6-tri-O-acetyl-2-azido-2-deoxy-alpha-D-galactopyranosyl)-L-serine/L-threonine pentafluorophenyl ester [Fmoc-L-Ser/L-Thr(Ac-3-alpha-D-GalN(3))-OPfP, 13/14] have been synthesized by two different routes, which have been compared. Overall isolated yields [three or four chemical steps, and minimal intermediary purification steps] of enantiopure 13 and 14 were 5-18% and 6-10%, respectively, based on 3,4,6-tri-O-acetyl-D-galactal (1). A byproduct of the initial azidonitration reaction of the synthetic sequence, that is, N-acetyl-3,4,6-tri-O-acetyl-2-azido-2-deoxy-alpha-D-galactopyranosylamine (5), has been characterized by X-ray crystallography, and shown by H-1 NMR spectroscopy to form complexes with lithium bromide, lithium iodide, or sodium iodide in acetonitrile-d(3). Intermediates 3,4,6-tri-O-acetyl-2-azido2-deoxy-alpha-D-galactopyranosyl bromide (6) and 3,4,6-tri-O-acetyl-2-azido-2-deoxy-beta-D-galactopyranosyl chloride (7) were used to glycosylate N-alpha-(9-fluorenylmethoxycarbonyl)-L-serine/L-threonine pentafluorophenyl esters [Fmoc-L-Ser/L-Thr-OPfp, 11/12]. Previously undescribed low-level dehydration side reactions were observed at this stage; the unwanted byproducts were easily removed by column chromatography. (c) 2005 Elsevier Ltd.

  The cycloaddition of azides to alkynes is one of the most important synthetic routes to 1H-[1,2,3]-triazoles. Here a novel regiospecific copper(I)-catalyzed 1,3-dipolar cycloaddition of terminal alkynes to azides on solid-phase is reported. Primary, secondary, and tertiary alkyl azides, aryl azides, and an azido sugar were used successfully in the copper(I)-catalyzed cycloaddition producing diversely

  highly reactive terminal ketocarbonyls were prone to aldol-type dimerization and could be transferred into stable moieties by oxime formation, reduction to the alcohol, or reductive amination, respectively. The alpha-ketocarbonyl peptides were efficient in nucleophilic addition of C-nucleophiles such as phosphono-ylides and allylsilanes.

  The synthesis of Fmoc-aminoacyl-N-ethyl-S-triphenylmethylcysteine, an N- to S-acyl migratory device for the preparation of peptide thioesters by Fmoc-SPPS (solid-phase peptide synthesis) is described. Condensation of Fmoc-aminoacyl pentafluorophenyl ester and N-ethyl-S-triphenylmethylcysteine was efficiently performed in the presence of HOOBt (3-hydroxy-3,4-dihydro-4-oxo-1,2,3-benzotriazine) in DMF. A small amount of diastereomer yielded during the reaction was easily separated by HPLC purification and the highly pure devices were obtained for most of the proteinogenic amino acids.
