Solvent-controlled regioselective protection of allyl-4,6-benzylidene glucopyranosides
نویسندگان
چکیده
We wish to report a simple synthetic procedure, which permits the regiospecific mono-acylation, alkylation and silylation at the 2-position of allyl 4,6-O-benzylidene alpha-D-glucopyranoside in high yields and which does not require the use of catalysts.

Regioselective synthesis of vinylic derivatives of common monosccarides through their activated stannylene acetal intermediates.
The regioselective C-2-O-acrylation and metacrylation of methyl 4,6-O-benzylidene-alpha-D-glucopyranoside and methyl 4,6-O-benzylidene-alpha-D-galactopyranoside through their corresponding organotin intermediates have been studied. Regioselectivity was achieved through the formation of a tin chelate of the 2,3-diols. Thus, methyl 4,6-O-benzylidene-alpha-D-glucopyranoside and methyl 4,6-O-benzyl...
متن کاملSynthesis of beta-D-glucose oligosaccharides from Phytophthora parasitica.
The glucohexaose, beta-D-Glcp-(1-->3)-[beta-D-Glcp-(1-->3)-beta-D-Glcp-(1-->3)-beta-D-Glcp-(1-->6)]-beta-D-Glcp-(1-->3)-D-Glcp, was synthesized as its allyl glycoside via 3+3 strategy. The trisaccharide donor, 2,3,4,6-tetra-O-benzoyl-beta-D-glucopyranosyl-(1-->3)-2,4,6-tri-O-acetyl-beta-D-glucopyranosyl-(1-->3)-2,4,6-tri-O-acetyl-alpha-D-glucopyranosyl trichloroacetimidate (11), was obtained by...
متن کاملSynthesis of Orthogonally Protected Muramic Acid Building Blocks for Solid Phase Peptide Synthesis
Muramic acid is found in many peptide natural products containing oligo(poly)saccharide moieties. Taking into consideration that the Fmoc methodology is routinely used for solid-phase peptide synthesis, preparation of orthogonally protected muramic acid building blocks for total solid-phase synthesis of these natural products is of particular practical importance. Herein a simple and efficient ...
متن کاملEfficient routes toward the synthesis of the D-rhamno-trisaccharide related to the A-band polysaccharide of Pseudomonas aeruginosa
The present work describes efficient avenues for the synthesis of the trisaccharide repeating unit [α-D-Rhap-(1→3)-α-D-Rhap-(1→3)-α-D-Rhap] associated with the A-band polysaccharide of Pseudomonas aeruginosa. One of the key steps involved 6-O-deoxygenation of either partially or fully acylated 4,6-O-benzylidene-1-thiomannopyranoside by radical-mediated redox rearrangement in high yields and reg...
