Solid phase synthesis of oligosaccharides

Tetrahedron Letters, 1996
Abstract An efficient and stereocontrolled solid-phase chemical synthesis of oligosaccarides using a new type of insoluble support (a copolymer of polyethylene glycol and polystyrene) is described. Several Lewis acids were tested as activators of the trichloroacetimidate 12 , used as glycosyl donor, in the dimer 13 formation.

Solid phase synthesis of benzimidazolones

Tetrahedron Letters, 1996
Abstract An efficient solid phase synthesis of benzimidazoles is described. Polymer bound o-fluoronitroaromatic compound 2 was treated with an amine to give o-nitroaniline derivative 3 . Reduction of 3 with NaBH 4 Cu(acac) 2 followed by cyclization with an aryl imidate and cleavage with TFA gave 5 .

Solid phase synthesis of quinolones

Bioorganic & Medicinal Chemistry Letters, 1999
Solid phase syntheses of ethyl 6-carboxyquinol-4(1H-)-one-3-carboxylate (5) and N-substituted 6-carboxyquinol-4(1H)-one-3-carboxamides 7a-d have been described. Antifilarial in vitro activities of 5,7a-d against Brugia malayi have also been delineated.

Solid‐phase synthesis of phosphopeptides

International Journal of Peptide and Protein Research, 1989
We report the solid‐phase synthesis of peptides containing O‐phosphoserine. Coupling was with commercially available Fmoc‐amino acid pentafluorophenyl esters, with base used at each cycle to cleave Fmoc. Phosphorylation of those serine residues left unprotected on the peptide‐resin was achieved with dibenzylphosphochloridate, and finally ...

Solid-Phase Synthesis of Solanesol

Journal of Combinatorial Chemistry, 2008
An efficient and convergent solid-phase strategy for the total synthesis of All- E solanesol is described. This method features avoidance of iterative and difficult purifications comparing with solution-phase synthesis and is suitable for the preparation of other oligoprenols.
