Highly enantioselective thiolysis of prochiral cyclic anhydrides catalyzed by amino alcohol bifunctional organocatalysts and its application to the synthesis of pregabalin

Asymmetric thiolysis of prochiral cyclic anhydrides was achieved with our developed chiral sulfonamide and squaramide bifunctional organocatalysts based on amino alcohol scaffolds. The corresponding thioesters were obtained in high yields with excellent enantioselectivities. The usefulness of this methodology was demonstrated in the enantioselective synthesis of pregabalin.

Novel amide-functionalized chloramphenicol base bifunctional organocatalysts for enantioselective alcoholysis of meso-cyclic anhydrides

A family of novel chloramphenicol base-amide organocatalysts possessing a NH functionality at C-1 position as monodentate hydrogen bond donor were developed and evaluated for enantioselective organocatalytic alcoholysis of meso-cyclic anhydrides. These structural diversified organocatalysts were found to induce high enantioselectivity in alcoholysis of anhydrides and was successfully applied to the asymmetric synthesis of (S)-GABOB.

Syntheses of alpha-d-galactosamine neoglycolipids

Several N-acetyl-alpha-d-galactosamine neoglycolipids, as well as hydrophobized T and TN antigen analogues, were prepared for embedment onto liposomes. Three different lipidic structures were used for the anchoring, that is cholesterol, 1,3-bis(undecyloxy)propan-2-ol and 1,3-bis(3,7,11,15-tetramethylhexadecyloxy)propan-2-ol. Oligoethyleneglycol spacers were used to link the carbohydrate and the hydrophobic moieties; their lengths were varied in order to obtain model compounds for the selective recognition by sialyl transferases involved in cancer processes. Glycosylation reactions were optimized to sluggish amphiphilic acceptor alcohols, in order to reach good 1,2-cis-stereoselectivities and acceptable yields. This aim was achieved by using 3,4,6-tri-O-acetyl-2-azido-2-deoxy-d-galactopyranosyl trichloroacetimidate as the donor, trimethylsilyl trifluoromethanesulfonate as the promoter and diethyl ether or mixtures of diethyl ether and dichloromethane as solvents.

Annulation of Hydrazones and Alkynes via Rhodium(III)-Catalyzed Dual C-H Activation: Synthesis of Pyrrolopyridazines and Azolopyridazines

Hydrazones readily synthesized from N-aminopyrroles or N-aminoazoles and aldehydes undergo Rh(III)-catalyzed dual C-H activation and coupling with aryl- A nd alkyl-substituted alkynes to give pyrrolopyridazines or azolopyridazines, respectively. This transformation represents a rare example of hydrazoyl C-H activation and proceeds without heteroatom functionality to direct C-H activation. Hydrazones derived from aromatic, alkenyl, and aliphatic aldehydes were effective inputs, and tethering the alkyne to the hydrazone enabled annulations to more complex, tricyclic products.

Metabolomic analysis of blood plasma after oral administration of N-acetyl-D-glucosamine in dogs

N-acetyl-D-glucosamine (GlcNAc) is a monosaccharide that polymerizes linearly through (1,4)-beta-linkages. GlcNAc is the monomeric unit of the polymer chitin. GlcNAc is a basic component of hyaluronic acid and keratin sulfate found on the cell surface. The aim of this study was to examine amino acid metabolism after oral GlcNAc administration in dogs. Results showed that plasma levels of ectoine were significantly higher after oral administration of GlcNAc than prior to administration (p < 0.001). To our knowledge, there have been no reports of increased ectoine concentrations in the plasma. The mechanism by which GlcNAc administration leads to increased ectoine plasma concentration remains unclear; future studies are required to clarify this mechanism. Note that a catalyst decreases the activation energy for both the forward and the reverse reactions and hence accelerates both the forward and the reverse reactions.HPLC of Formula: C8H15NO6, you can also check out more blogs about14215-68-0
