Efficient synthesis of 3-aminocyclobut-2-en-1-ones: Squaramide surrogates as potent VLA-4 antagonists

(Matrix presented) A novel series of uniquely functionalized 3-aminocyclobut-2-en-1-ones has been prepared by facile condensation of a variety of cyclobuta-1,3-diones with a phenylalanine-derived primary amine. These systems subsequently lend themselves to substitution at C-2 by reaction with a variety of electrophilic reagents including N-halosuccinimides, sulfenyl chlorides, and Eschenmoser’s salt.

CARDIAC GLYCOSIDES: 5. STEREOSELECTIVE SYNTHESES OF DIGITOXIGENIN alpha-D, beta-D, alpha-L AND beta-L-GLUCOSIDES

As part of a continuing study of cardiac glycosides, stereoselective syntheses of the four possible glucosides of digitoxigenin were developed via the thermodynamically produced tetra-O-benzyl-D- and L-glucosyl alpha-trichloroacetaimidates 2alpha and 11alpha, and the kinetically produced beta-trichloroacetaimidates 2beta and 11beta.A 58percent:19percent isolated yield ratio of alpha-D and beta-D benzyl protected glycosides 6 and 3 could be obtained in 30 minutes reaction at -10 deg.Halide ion catalysis with a 2:1 excess of tetra-O-benzyl-alpha-D-glucopyranosyl bromide for 14 days in methylene chloride at room temperature gave a 39percent:11percent ratio of 6 and 3, along with 43percent of recovered digitoxigenin.Debenzylation of the D-glucosides required milder conditions (20percent Pd/C, atmospheric pressure, 45 min – 1 hr) than the L-glucosides (40percent Pd/C, 2 hr) but yields were typically 80percent for both groups.

C?H Insertion as a Key Step to Spiro-Oxetanes, Scaffolds for Drug Discovery

A new route to spiro-oxetanes, potential scaffolds for drug discovery, is described. The route is based on the selective 1,4-C?H insertion reactions of metallocarbenes, generated from simple carbonyl precursors in flow or batch mode, to give spiro-beta-lactones that are rapidly converted into spiro-oxetanes. The three-dimensional and lead-like properties of spiro-oxetanes are illustrated by the conversion of the 1-oxa-7-azaspiro[3,5]nonane scaffold into a range of functionalized derivatives.

The proportionality constant is the rate constant for the particular unimolecular reaction. the reaction rate is directly proportional to the concentration of the reactant. I hope my blog about 2081-44-9 is helpful to your research., Reference of 2081-44-9

Selective deacetylation using iodine-methanol reagent in fully acetylated nucleosides

Selective deprotection of primary acetyl ester in nucleosides and carbohydrates using 1% iodine-methanol solution (w/v) was described and the mechanism was also discussed.

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.category: Tetrahydropyrans, you can also check out more blogs about28244-94-2

A direct, heavy metal free synthesis of the beta-1,6-linked GlcNAc disaccharide

The major component of the matrix of many bacterial biofilms is a linear polymer of beta-1,6-linked units of N-acetylglucosamine (polysaccharide intercellular adhesin or poly-N-acetylbeta – 1,6-D-glucosamine). In order to facilitate synthetic vaccine construction we have developed a direct, inexpensive, and biologically compatible synthesis of the minimal building block of this polymer, a beta -1,6-linked GlcNAc disaccharide, namely 6-O-[2-acetamido-2-deoxy – beta-D-glucopyranosyl]-2-acetamido-2-deoxy-D- glucopyranose.

Application of 499-40-1, Chemistry can be defined as the study of matter and the changes it undergoes.

Construction of Zn(II)-ferrocenyl carboxylate coordination complexes via changing adjuvant ligands

Single-crystal X-ray analysis reveals that 1 and 2 are mononuclear structures, 3 is a dimer, and 4 and 5 are 1-D structures. The five complexes exhibit some differences in their conformations, which can be attributed to the influence of adjuvant ligands. Notably, various pi-interactions as well as CH/piinteractions are discovered in 1-5, and they have significant contributions to self-assembly. The electrochemical properties of 1-5 indicate that half-wave potentials shift to positive potential compared with that of 2-chloro-4-ferrocenylbenzoic acid.
