Chromium(II) Amides: Synthesis and Structures

A novel class of mono- and di-meric chromium(II) amides has been prepared and characterized.Reaction of (thf = tetrahydrofuran) with 2 equivalents of M(NR2) (R = C6H11, Pri, Ph, or phenothiazinyl; M = Li or Na) allowed the formation of the homoleptic amides <2> (R = Ph 1a, C6H11 1b or Pri 1c).The reaction is followed by co-ordination of a Lewis base which, although preserving the Cr2(NR2)2 core, remarkably elongated the Cr…Cr distance forming <2> (R = Ph, L = thf 2).Facile cleavage to give the square-planar monomeric species (R = Ph, L = pyridine 3a, thf 3b; NR2 = phenothiazinyl, L = thf 3c) occured upon treatment with an excess of co-ordinating solvent.Reaction with an excess of M(NR2) led to the formation of anionic chromium(II) square-planar metalates (R = Ph, M = Na, L = thf 4a; R = Et, M = Li, L = thf 4b or pyridine 4c).A dimeric species with a very short Cr…Cr contact <2>2>*2dmf (dmf = dimethylformamide) 5b has been obtained involving a unique three-centre chelating geometry of the bridging amide ligand.The crystal structures of compounds 1b, 2, 3a, 3c, 4c and 5b have been determined.

Chemical synthesis of 6”’-alpha-maltotriosyl-maltohexaose as substrate for enzymes in starch biosynthesis and degradation

A branched nonasaccharide 6”’-alpha-maltotriosyl-maltohexaose was synthesised in 40 steps from D-glucose and maltose. Phenyl O-(2,3,4,6-tetra-O-benzyl-alpha-D-glucopyranosyl)-(1?4)-O-(2,3,6-tri-O-benzyl-alpha-D-glucopyranosyl)-(1?4)-2,3-di-O-benzyl-1-thio-beta-D-glucopyranoside and O-(2,3,4,6-tetra-O-benzyl-alpha-D-glucopyranosyl)-(1?4)-O-(2,3,6-tri-O-benzyl-alpha-D-glucopyranosyl)-(1?4)-2,3,6-tri-O-benzyl-alpha,beta-D-glucopyranosyl trichloroacetimidate were coupled by a general condensation reaction to form the per-O-benzylated branched hexasaccharide phenyl thioglycoside. The phenylthio group of this compound was converted into a trichloroacetimidate, which was coupled with phenyl O-(2,3,6-tri-O-benzyl-alpha-D-glucopyranosyl)-(1?4)-O-(2,3,6-tri-O-benzyl-alpha-D-glucopyranosyl)-(1?4)-2,3,6-tri-O-benzyl-1-thio-beta-D-glucopyranoside to afford the per-O-benzylated branched nonasaccharide phenyl thioglycoside. Replacement of the phenylthio group with a free OH-group followed by hydrogenolysis gave the desired product. The synthons reported for this synthesis constitute a versatile tool for the chemical synthesis of other complex carbohydrates. Copyright (C) 1999 Elsevier Science Ltd.

Efficient chemoenzymatic synthesis of novel galacto-N-biose derivatives and their sialylated forms

Galacto-N-biose (GNB) derivatives were efficiently synthesized from galactose derivatives via a one-pot two-enzyme system containing two promiscuous enzymes from Bifidobacterium infantis: a galactokinase (BiGalK) and a d-galactosyl-beta1-3-N-acetyl-d-hexosamine phosphorylase (BiGalHexNAcP). Mono-sialyl and di-sialyl galacto-N-biose derivatives were then prepared using a one-pot two-enzyme system containing a CMP-sialic acid synthetase and an alpha2-3-sialyltransferase or an alpha2-6-sialyltransferase.

Iron(iii) chloride modulated selective 1,2-trans glycosylation based on glycosyl trichloroacetimidate donors and its application in orthogonal glycosylation

The development of a new glycosylation method for efficient stereoselective synthesis of beta-gluco- and galactosides from their corresponding armed trichloroacetimidate donors mediated by 10 mole% of FeCl3 has been focused. FeCl3 has also been applied to a number of glucose, galactose, mannose and rhamnose based trichloroacetimidate donors with various protecting groups incorporated at the C-2-position to prepare a variety of disaccharides and trisaccharides with excellent 1,2-trans selectivity. FeCl3 can also modulate the 1,2-trans selectivity of the reaction of 2-O-alkylated gluco- and galacto-pyranosyl trichloroacetimidates with phenolic compounds leading to the generation of the corresponding beta-O-aryl glycosides in excellent yield and selectivity. Apart from these the present methodology has been successfully utilized for double glycosylation and orthogonal glycosylation reactions along with its application in one-pot three component orthogonal glycosylation reactions for synthesis of a trisaccharide.

Affinity enhancement by dendritic side chains in synthetic carbohydrate receptors

Dendritic side chains have been used to modify the binding environment in anthracene-based synthetic carbohydrate receptors. Control of length, charge, and branching enabled the positioning of side-chain carboxylate groups in such a way that they assisted in binding substrates rather than blocking the cavity. Conformational degeneracy in the dendrimers resulted in effective preorganization despite the flexibility of the system. Strong binding was observed to glucosammonium ions in water, with Ka values up to 7000 m -1. Affinities for uncharged substrates (glucose and N-acetylglucosamine) were also enhanced, despite competition from solvent and the absence of electrostatic interactions.

Synthesis of N-linked glycosyl asparagine derivatives with unprotected sugar components

A general methodology for the efficient formation of N-glycosidic linkage to asparagine (Asn), which, does not require the protection of sugar component hydroxyl groups is described. Aspartic acid fluoride was used in combination with N-allyloxycarbonyl (Alloc) glycosyl amines. Pd(0)-PhSiH3 mediated in situ Alloc removal-coupling was performed in aqueous solution dioxane to give Asn-linked carbohydrates in high yield.

Alkyl substituted aminal derivatives of HCV NS5A inhibitor MK-8742

HCV NS5A inhibitors have demonstrated impressive in vitro potency profiles in HCV replicon assays and robust HCV RNA titer reduction in the clinic making them attractive components for inclusion in an all oral fixed dose combination regimen for the treatment of HCV infection. Herein we describe our continued research efforts around the alkyl ?Z group? modification of the tetracyclic indole-based NS5A inhibitor MK-8742, which led to the discovery of a series of potent NS5A inhibitors. Compounds 10 and 19 are of particular interests since they are as potent as our previous leads and have much improved rat pharmacokinetic profiles.
