Stereoselective synthesis of Z, E conjugated dienes: Application to the synthesis of insect sex pheromones

Stereoselective synthesis of insect pheromone components 1-5, p possessing Z,E conjugated diene system has been developed using 1,3-enynes (generated by the in situ alkylation of dianion of prop-2-yn-1-ol followed by Horner-Witting reaction) as precursors.

Synthesis and biological activity of glycosyl-1H-1,2,3-triazoles

Glycosyl 1,2,3-triazoles with alpha-d-gluco, beta-d-gluco, alpha-d-galacto, beta-d-galacto and beta-2-acetamido-2-deoxygluco (GlcNAc) stereochemistry were prepared by reaction of the corresponding azides with vinyl acetate under microwave irradiation. The deprotected glucosyl and galactosyl triazoles did not display inhibitory activity against the tested glycosidases at 1 mM. Of the four fungal glycosidases evaluated, GlcNAc-triazole was found to be hydrolyzed by Talaromyces flavus CCF 2686 beta-N-acetylhexosaminidase. beta-GlcNAc-triazole was furthermore established to act as a strong ligand of rat and human natural killer cell activating receptors.

The formal total synthesis of FR252921-An immunosuppressant

The formal total synthesis of FR252921 is described. The key steps include the preparation of three fragments starting from 1,4-butanediol, (R)-malic acid, and prenol, respectively, followed by two consecutive peptide couplings of the three fragments. Other key steps involve an allene-type rearrangement or enyne isomerization to install the triene moiety, a Seebach methylation, a Julia olefination to construct the trisubstituted diene unit, and an enzymatic resolution strategy to generate the C-18 stereocenter.

Synthesis, Characterization, and Stereochemistry of Bridged Intramolecularly Alkylated Cobaloximes; Monomeric and Dimeric Complexes of Different Configuration

Ligands have been synthesized containing two vicinal dioxime functions joined by a carbon chain to which is attached in the centre a bromomethyl or chloromethyl group (20, 22, 25).These ligands, upon reaction with cobalt(II) chloride in the presence of pyridine and sodium borohydride afforded bridged intramolecularly alkylated cobaloximes.When the vicinal dioxime functions are separated by a chain of nine carbon atoms mainly dimeric complexes are formed.Two of these, 26 and 27, were isolated and characterized by spectroscopic methods and their structures were established by X-ray crystallography.Ligands containing eleven or thirteen carbon atoms between the dioxime functions afforded mainly monomeric cobaloximes with cis configuration, e. g. 28.The trans-monomeric complex 30 was produced along with the cis isomer when the number of carbon atoms in the bridge was raised to fifteen.

Discovery of structurally simplified analogs of colchicine as an immunosuppressant

We have discovered a new class of colchicine-derived therapeutic agents for immune diseases including rejection of organ-transplantation and autoimmune disease. Compound 2, which had been developed to overcome poor pharmacokinetic properties of compound 1, a first-generation colchicine analog, turned out to show toxicity such as intestinal toxicity and loss of weight during in vivo tests. The deletion of 7-carboxamide group and middle ring-truncation in colchicine allowed us to have structurally simplified analogs with strong immunosuppressive activity. Herein, we report non-alkaloid tricyclic compound 7 and 12 as immunosuppressants which exhibited a strong immunosuppressive in vivo efficacy on the T-dependent antibody response, the Zymosan A-induced arthritis model and the Carrageenan-induced edema model. Compound 7 and 12 revealed less toxicity than the previous lead compound 2, and their minimum lethal doses (MLD) were proved to exceed 100 mg/kg.

Sulfonylation-induced N-to O -Acetyl migration in 2-acetamidoethanol derivatives

The first example of sulfonylation-induced N- to O-acetyl migration of 2-acetamidoethanol derivatives is described. This type of reaction could happen with any 2-acetamidoethanol derivatives under typical sulfonylation conditions (TsCl or MsCl, pyridine) and might be a common side reaction of significance. Furthermore, the results reveal that 2-acetamidoethanol derivatives with a sterically encumbered hydroxyl group result in the migration products in high yields. The mechanism of the migration reaction is discussed.

Enzymatic synthesis and characterization of 6-O-beta-D-xylopyranosyl-2-acetamido-2-deoxy-D-glucopyranose, a structural analog of primeverose

The synthesis of the disaccharide 6-O-beta-D-xylopyranosyl-2-acetamido-2-deoxy-D-glucopyranose (N-acetylprimeverosamine), structurally related to the natural disaccharide 6-O-beta-D-xylopyranosyl-D-glucopyranose (primeverose), was obtained via a transglycosylation reaction catalyzed by a crude preparation of beta-D-xylosidase from Aspergillus niger, using p-nitrophenyl beta-D-xylopyranoside as the donor and 2-acetamido-2-deoxy-D-glucopyranose as the acceptor. The yield of the reaction was 36% on a molar basis with respect to the donor. The chemical identity of the product was assessed by HPLC, ionspray mass spectrometry and NMR spectroscopy.

Synthesis of 6-, 7- and 8-carbon sugar analogues of potent anti-influenza 2,3-didehydro-2,3-dideoxy-N-acetylneuraminic acid derivatives

Analogues of the potent anti-influenza A and B compound, 4-guanidino-Neu5Ac2en, are described in which the stereochemically demanding C-6-glycerol side-chain is truncated.Syntheses of the one- and two-carbon side-chain analogues, of both 4-guanidino- and 4-amino-Neu5Ac2en, are presented, as well as the syntheses of analogues lacking any side-chain.Whilst complete removal of the C-6 side-chain abolishes activity, a stepwise increase in inhibition of influenza neuraminidase and influenza A and B in cell culture with increasing C-6 chain length is observed.The one-carbon, hydroxymethyl derivative retains significant activity to represent a suitable lead in the search for neuraminidase inhibitors of reduced stereochemical demand and synthetic complexity.
