Practical synthesis of the 2-acetamido-3,4,6-tri-O-acetyl-2-deoxy-beta-D-glucosides of Fmoc-serine and Fmoc-threonine and their benzyl esters.[Pubmed:12706969]
Carbohydr Res. 2003 May 1;338(10):1039-43.
Mercuric bromide-promoted glycosylation of Fmoc-Ser-OBn and Fmoc-Thr-OBn with 2-acetamido-2-deoxy-3,4,6-tri-O-acetyl-alpha-D-glucopyranosyl chloride in refluxing 1,2-dichloroethane gave the corresponding beta-glycosides in good yields (64 and 62%, respectively). Direct coupling of the commercially available Fmoc-Ser-OH and Fmoc-Thr-OH carboxylic acids under similar conditions gave the corresponding beta-glycosides, possessing free carboxyl groups, in moderate yields (50 and 40%, respectively).
Construction and structural characterization of versatile lactosaminoglycan-related compound library for the synthesis of complex glycopeptides and glycosphingolipids.[Pubmed:17168577]
J Org Chem. 2006 Dec 22;71(26):9609-21.
We have established a facile and efficient protocol for the preparative-scale synthesis of various compound libraries related to lactosaminoglycans: cell surface oligosaccharides composed of N-acetyllactosamine as a repeating disaccharide unit, based on chemical and enzymatic approaches. Substrate specificity and feasibility of a bacterial glycosyltransferase, Neisseria meningitidis beta1,3-N-acetylglucosaminyltransferase (LgtA), were investigated in order to synthesize various key intermediates suited for the construction of mammalian O-glycopeptides and glycosphingolipids containing poly-N-acetyllactosamine structures. Recombinant LgtA exhibited the highest glycosyltransferase activity with strongly basic conditions (pH = 10, glycine-NaOH buffer) and a broad range of optimal temperatures from 20 to 30 degrees C. Interestingly, it was found that LgtA discriminates L-serine and L-threonine and functions both as a core-1 beta1,3-N-acetylglucosaminyltransferase and core-2 beta1,3-N-acetylglucosaminyltransferase toward Fmoc-Ser derivatives, while LgtA showed only core-2 beta1,3-N-acetylglucosaminyltransferase activity in the presence of Fmoc-Thr derivatives. Combined use of LgtA with human beta1,4-galactosyltransferase allowed for controlled sugar extension reactions from synthetic sugar amino acids and gave synthetic lactosaminoglycans, such as a decasaccharide derivative, Galbeta(1 --> 4)GlcNAcbeta(1 --> 3)Galbeta(1 --> 4)GlcNAcbeta(1 --> 3)Galbeta(1 --> 4)GlcNAcbeta(1 --> 3)Galbeta(1 --> 4)GlcNAcbeta(1 --> 6)[Galbeta(1 --> 3)]GalNAcalpha1 --> Fmoc-Ser-OH (6), and a dodecasaccharide derivative, Galbeta(1 --> 4)GlcNAcbeta(1 --> 3)Galbeta(1 --> 4)GlcNAcbeta(1 --> 3)Galbeta(1 --> 4)GlcNAcbeta(1 --> 6)[Galbeta(1 --> 4)GlcNAcbeta(1 --> 3)Galbeta(1 --> 4)GlcNAcbeta(1 --> 3)Galbeta(1 --> 3)]GalNAcalpha1 --> Fmoc-Ser-OH (9). A partially protected pentasaccharide intermediate, GlcNAcbeta(1 --> 3)Galbeta(1 --> 4)GlcNAcbeta(1 --> 6)[Galbeta(1 --> 3)]GalNAcalpha1 --> Fmoc-Thr-OH (11), was applied for the microwave-assisted solid-phase synthesis of a MUC1-related glycopeptide 19 (MW = 2610.1). The findings suggest that this sugar extension strategy can be employed for the modification of lactosyl ceramide mimetic polymers to afford convenient precursors for the synthesis of various glycosphingolipids.
Efficient solid phase synthesis of mixed Thr(P)-, Ser(P)- and Tyr(P)-containing phosphopeptides by "global" "phosphite-triester" phosphorylation.[Pubmed:1280250]
Int J Pept Protein Res. 1992 Aug;40(2):134-40.
The synthesis of the mixed Thr(P)/Tyr(P)-containing peptide, Ala-Thr(P)-Tyr(P)-Ser-Ala, was accomplished by "phosphite-triester" phosphorylation of the resin-bound Thr/Tyr-containing peptide using di-t-butyl N,N-diethylphosphoramidite as the phosphitylation reagent. The pentapeptide-resin was assembled by Fmoc/solid-phase peptide synthesis with the use of PyBOP as coupling reagent and the hydroxy-amino acids incorporated as side-chain free Fmoc-Tyr-OH and Fmoc-Thr-OH. "Global" bis-phosphorylation of the peptide-resin was accomplished by treatment with di-t-butyl N,N-diethylphosphoramidite/1H-tetrazole followed by m-chloroperoxybenzoic acid oxidation of the intermediate di-t-butylphosphite triester. Simultaneous peptide-resin cleavage and peptide deprotection was effected by treatment of the peptide-resin with 5% anisole/TFA and gave the Thr(P)/Tyr(P)-containing phosphopeptide in high yield and purity. In addition, the tyrosyl residue was found to be phosphitylated in preference to the threonyl residue since the phosphitylation of the pentapeptide-resin using only 1.1 equiv. of di-t-butyl N,N-diethylphosphoramidite gave Ala-Thr-Tyr(P)-Ser-Ala as the major product and both Ala-Thr(P)-Tyr(P)-Ser-Ala and Ala-Thr-Tyr-Ser-Ala as minor products.
