Allyl 2,3,4-tri-O-allyl-D-glucopyranuronate (7) has been prepared (overall yield, 37percent) from methyl 1,2,3,4-tetra-O-acetyl-alpha- or -beta-D-glucopyranuronate via a six-step reaction procedure. 1-O-Acetyl-, 1-O-methacroyl-, and 1-O-phenylacetyl-alphabeta-D-glucopyranuronic acid are produced by esterification of 7 and removal of the allyl groups with palladium-on-carbon in an acidic medium.The reaction of 7 with the di-imidazole derivative of bilirubin yields the allyl-protected mono-, and di-D-glucopyranosyluronic acid derivatives of bilirubin.Neither the bilirubin nor the corresponding biliverdin derivatives resisted the conditions required for de-allylation.

We demonstrate that an extended scaffold based on a self-immolative linker (SIL) enables the universal production of O-aryl glucuronide prodrugs: high yield glucuronidation is performed on a precursor substrate (SIL) and the subsequent drug conjugation proceeds via less challenging chemical reactions.

Lanthanide triflates, especially Nd(OTf)3, efficiently catalyze the regioselective transesterification of anomeric acetates. This method offers an efficient solution for the otherwise difficult removal of methyl uronates anomeric acetates as well as a green alternative to published protocols since the lanthanide catalysts are non-toxic and may be easily recycled and reused.

The synthesis of the fully benzylated alpha- and beta-D-glucopyranosyluronic esters of 1-benzyl N-benzyloxycarbonyl-L-aspartic and glutamic acids and N-(tert-butoxycarbonyl)-L-phenylalanine, followed by hydrogenolysis, afforded the respective anomers of the 1-O-acyl-D-glucopyranuronic acids 2, 7, and 12.Esterification of both anomers of the N-acetylated derivatives of 2 and 7 by diazomethane was accompanied by glycosyl-bond cleavage and in the case of the alpha anomers, with concomitant 1-2 acyl migration to give, after O-acetylation, the 2-O-acyl O-acetyl methyl ester derivatives 5 and 10, respectively.Similarly, 12alpha yielded methyl 1,3,4- tri-O-acetyl-2-O--D-glucopyranuronate and an analogue having a furanurono-6,3-lactone structure.Esterification of the C-5 carboxyl group in 1-O-acyl-alpha-D-glucopyranuronic acids by methanol in presence of the BF3-MeOH reagent (1-1.5 equiv.) proceeded without acyl migration.By using this procedure, followed by acetylation, the N-acetylated derivative of 7alpha afforded methyl 2,3,4-tri-O-acetyl-1-O-(1-methyl N-acetyl-L-glutam-5-oyl)-alpha-D-glucopyranuronate, and 12alpha gave methyl 2,3,4-tri-O-acetyl-1-O-(N-acetyl-L-phenylalanyl)-alpha-D-glucopyranuronate; the formation of the latter involved cleavage of the tert-butoxycarbonyl group by BF3, followed by N-acetylation in the next step.

The polymorphism of the glycoside donor methyl 2,3,4-tri-O-acetyl-1-O- (trichloroacetimidoyl)-alpha-d-glucopyranouronate (1) has been investigated. Two polymorphic forms (labelled Forms I and II) have been elucidated and fully characterised by DSC, PXRD and single crystal analysis, both crystallizing in the space group P21. Form I was obtained by crystallization from a wide range of solvents, while Form II was obtained only from ethyl acetate or isopropanol on certain occasions. Unit cell dimensions for Form I are a 14.0292(12), b 8.9641(8), c 16.8580(14) A, beta 94.285(2), and for Form II a 11.266(3), b 6.8889(17), c 13.921(4) A, beta 101.161(6). Z’ is 2 for Form I and 1 for Form II. Form I displays two moderate intermolecular hydrogen bonds in the unit cell whereas Form II shows no moderate hydrogen-bonding motifs. All three molecules in the two polymorphs differ significantly in their conformations, especially with respect to the methyl carboxylate and trichloroacetimidoyl groups.

Design and synthesis of dimeric heparinoid mimetics

Synthetic oligosaccharide constructs exhibiting tailored and well-defined heparan sulfate (HS) like sequences offer the potential to modulate dynamic HS-dependent biomolecular recognition processes. We report an efficient strategy for the generation of HS-like fragments [GlcA-beta-(1,4)-GlcNAc] and related dimerized (gemini) disaccharides (4a and 4b) via n-pentenyl glycoside formation. When a convergent synthetic approach was utilized, construction of target molecules was achieved through a combination of chemoselective protection/deprotection protocols, imidate and n-pentenyl glycosylations, and functional group manipulations followed by ozonolysis and reductive amination. For example, glycosylation of a 2-azido glycoside (25) with a trichloroacetimidate glucuronic acid donor (13), using a catalytic amount of TMSOTf, furnished heparin-like disaccharides (28a and 28b) that were equipped with an n-pentenyl tether at the anomeric end. In turn, heparinoid-like gemini disaccharides (4a and 4b) were produced by selective transformation of the olefinic unit in the n-pentenyl glycoside to the four-carbon aldehyde followed by reductive amination with ethylene-diamine. The described synthetic approach provides access to structural variants of small heparinoid oligomers as versatile building blocks for generating novel HS mimetic pharmacotherapeutics, diagnostic reagents, and biomaterials.

Total synthesis of CRM646-A and -B, two fungal glucuronides with potent heparinase inhibition activities

CRM646-A (1) and -B (2), two fungal glucuronides with a dimeric 2,4-dihydroxy-6-alkylbenzoic acid (orcinol p-depside) aglycone showing significant heparinase and telomerase inhibition activities, were synthesized for the first time. The successful approach involved construction of the phenol glucuronidic linkage, via coupling of the orsellinate derivative 27 with glucuronate bromide 7, before assembly of the phenolic ester linkage in the depside aglycone. Attempts via direct glycosylation of the depside aglycone derivatives were not successful.
