The expedient and stereoselective syntheses of small libraries of trifunctionalized cyclobutane scaffolds bearing an acid, an amine, and a third functional group are described. Starting from a single precursor, the readily available protected derivative of all-cis-2-amino-3-hydroxycyclobutane-1-carboxylic acid, cis-trans stereoisomers are obtained following an S(N)2-type reaction, while all-trans stereoisomers are obtained using the same strategy preceded by a C1 epimerization reaction.

With the infection rate of Bordetella pertussis at a 60-year high, there is an urgent need for new anti-pertussis vaccines. The lipopolysaccharide (LPS) of B. pertussis is an attractive antigen for vaccine development. With the presence of multiple rare sugars and unusual glycosyl linkages, the B. pertussis LPS is a highly challenging synthetic target. In this work, aided by molecular dynamics simulation and modeling, a pertussis-LPS-like pentasaccharide was chemically synthesized for the first time. The pentasaccharide was conjugated with a powerful carrier, bacteriophage Q beta, as a vaccine candidate. Immunization of mice with the conjugate induced robust anti-glycan IgG responses with IgG titers reaching several million enzyme-linked immunosorbent assay (ELISA) units. The antibodies generated were long lasting and boostable and could recognize multiple clinical strains of B. pertussis, highlighting the potential of Q beta-glycan as a new anti-pertussis vaccine.

A convenient and efficient strategy for the synthesis of 2-acyl benzothiazoles/thiazoles has been developed. The treatment of benzothiazole/thiazole with allylic Grignard reagents readily generates the corresponding 2-Grignard reagents, which is followed by a reaction with N,N’-carbonyldiimidazole activated carboxylic acids to afford various 2-acyl benzothiazoles/thiazoles products. The synthetic method is applicable to a wide array of carboxylic acids and allows easy access to 2-acyl benzothiazoles/thiazoles with considerable yields under mild reaction conditions.

We describe the synthesis of 10-aza-9-oxakalkitoxin, an N,N,O-trisubstituted hydroxylamine-based analog, or hydroxalog, of the cytotoxic marine natural product kalkitoxin in which the -NMe-O- moiety replaces a -CHMe-CH2- unit in the backbone of the natural product. 10-Aza-9-oxakalkitoxin displays potent and selective cytotoxicity (IC50 2.4 ng mL(-1)) comparable to that of kalkitoxin itself (IC50 3.2 ng mL(-1)) against the human hepato-carcinoma cell line HepG2 over both the human leukemia cell line CEM and the normal hematopoietic CFU-GM. Like kalkitoxin, and contrary to the common expectation for hydroxylamines, 10-aza-9-oxakalkitoxin is not mutagenic.

This article describes a Lewis-acid-promoted semi-pinacol rearrangement of chiral epoxy alcohols to provide chiral beta-hydroxy aldehydes with a quaternary center at the alpha-position that are otherwise difficult to access in modern organic synthesis. The aldehydes thus obtained are highly useful synthetic intermediates, which is demonstrated by the synthesis of a serotonin antagonist.

In the present study, iron oxide magnetic nanoparticles (Fe3O4 MNPs) were synthesized in a green biosynthetic manner using aqueous extract of clover leaves. Fe3O4 MNPs were applied as a magnetically separable nanocatalyst for the green syntheses of functionalized [1,3]-oxazoles 1(a-e) and 1H-pyrrolo-[1,3]-oxazoles 4(a-i) as promising antioxidant compounds in excellent yields at 50 degrees C and room temperature, respectively. The antioxidant activities of the most stable compounds (1a, 1b, 4a, and 4b) were evaluated by both 2,2-diphenyl-1-picrylhydrazyl radical scavenging and ferric reduction activity potential assays. Compound 1b was shown a remarkable radical scavenging activity, and 4a was shown very good reducing activity relative to standards (BHT and TBHQ). [GRAPHICS] .

A rhodium catalyzed copper mediated double oxidative annulation of propargylamino phenyl benzamides is developed. A quick assembly of tri, tetra and penta cyclic pyrido/isoquinolo-quinoxilines are thus achieved from readily available linear substrates. The reaction is shown to be very general by accommodating a large variety of substrates in the transformation. A mechanism through an amide directed C-H bond activation followed by an intramolecular alkyne activation/annulation followed by an oxidation is postulated.

The oxidative coupling of carboxylic acids with liquid ketones and cyclic ethers has been accomplished in minutes using t-butyl hydroperoxide in the presence of tetrabutylammonium iodide under microwave irradiation in the absence of a solvent. In addition to drastically shortening the reaction times, the use of microwaves resulted, in general, in yields equal to or higher than those obtained by conventional heating.

The present work describes the preparation of two ionic liquid and carboxyl acid silane reagents via photo-initiated thiol-ene click chemistry that have been bonded to silica to afford two mixed-mode stationary phases (Sil-C4Im-C9Co and Sil-C9Im-C4Co). The two stationary phases provided satisfactory retention repeatability and efficiencies. The influence of acetonitrile content, salt concentration and pH of the mobile phase was investigated to clarify the retention properties of the prepared stationary phases. The results showed that the prepared Sil-C4Im-C9Co and Sil-C9Im-C4Co undergo multiple interactions with solutes under different chromatographic conditions. The retention mechanisms were further studied by the linear energy solvation relationship and Van’t Hoff plots. Finally, the stationary phases were employed to separate hydrophobic solutes (alkylbenzenes and polycyclic aromatic hydrocarbons) under reversed phase liquid chromatography (RPLC) mode, hydrophilic solutes (carboxylic acids, nucleosides and bases) under hydrophilic interaction liquid chromatography (HILIC) mode and inorganic anions under ion-exchange chromatography (IEC) mode, providing excellent performance and varying selectivity when compared with a commercial column. The bonding method in this work is feasible and the prepared stationary phases are promising when employed in RPLC/HILIC/IEC mixed-mode chromatography applications. (C) 2019 Elsevier B.V.
