Microwave-Assisted Metal-Free Decarboxylative Iodination/Bromination of Isoxazole-4-carboxylic Acids

A microwave-assisted metal-free route to substituted 4-haloisoxazoles via decarboxylative halogenation of substituted isoxazole-4-carboxylic acids using N-iodosuccinimide (NIS) and N-bromosuccinimide (NBS) in the presence of K3PO4 is described. It was discovered that the substitutions present at the 3-position of differently 3,5-disubstituted isoxazoles influenced the outcome of the protocol. The methodology is compatible for performing decarboxylative halogenation followed by decarboxylative Suzuki-Miyaura and Sonogashira couplings as one-pot process.

Synthesis of 4-(2-hydroxyphenyl)-5,6,7,8-tetrahydroisoxazolo[5,4-b]chromene-5(4H)-ones

The aim of this work is the synthesis of new tetraheterocyclic compounds of interest as potential biologically active substances that include the isoxazole and chromone moieties in their structure. The synthesis of such compounds was carried out with two stages. By Knoevenagel condensation of 3-methyl-1,2-isoxazol-5(2H)-on with salicylic aldehyde (4Z)-4-(2-hydroxybenzyliden)- 3-methyl-1,2-oxazol-5(4H)-on was obtained. In this reaction an excess of half of the aldehyde equivalent was used to increase the yield of the product. Pyperidine was used as a catalyst. The reaction was carried out by boiling the components in ethyl acetate. The reaction of the resulting benzylidenisoxazole derivative with cyclohexane-1,3-dione or dimedone was performed by boiling the components in ethanol without the use of a catalyst. The interaction mechanism includes heterodiene Dielsa-Aldera condensation followed by dehydration of one water molecule. As a result, 3-methyl-4-(2-hydroxyphenyl-5,6,7,8-tetrahydroisoxazolo[5,4-b]chromene-5(4H)-one and 3,7,7-trimethyl-4-(2-hydroxyphenyl)-5,6,7,8,9-tetrahydroisoxazolo[5,4-b]chromen-5(4H)-one were obtained. Purification of the synthesized compounds was carried out by crystallization from ethanol. All the obtained compounds were characterised by IR 1H NMR and UV spectroscopies. In 1H NMR spectra there are signals of the methyl groups of the isoxazole ring of compounds at 2.26, 2.29, 2.34 ppm respectively. In the UV spectrum of a plane molecule of (4Z)-4-(2- hydroxybenzyliden)-3-methyl-1,2-oxazol-5(4H)-on there is a long-wave absorption maximum (400.9 nm) corresponding to the joint system of conjugated bonds of the isoxazole and aromatic rings. The structures of the obtained compounds were confirmed by high resolution massspectrometry analysis. In the spectra of 3-methyl-4-(2-hydroxyphenyl-5,6,7,8-tetrahydroisoxazolo[5,4- b]chromene-5(4H)-one and 3,7,7-trimethyl-4-(2-hydroxyphenyl)-5,6,7,8,9-tetrahydroisoxazolo[5,4- b]chromen-5(4H)-one the[M + Na]+ ion peaks were observed. The presence of fragment peaks [M + Na – CO]+ and [M + Na – CO – H2O]+ confirms the presence of hydroxy and carbonyl groups in the molecules.

Acid/Base-Co-catalyzed Direct Oxidative alpha-Amination of Cyclic Ketones: Using Molecular Oxygen as the Oxidant

A novel acid/base-co-catalyzed direct intermolecular alpha-amination of various cyclic ketones has been developed for the first time. The reaction employs molecular oxygen as the sole oxidant under metal-free conditions. The reaction tolerates a wide range of various anilines, especially primary diamine derivatives, and provides a simple and efficient method for the constructions of alpha-amino enones and benzodiazepine derivatives in a single step. (Figure presented.).

Synthesis and cytoprotective characterization of 8-hydroxyquinoline Betti products

The 8-hydroxyquinoline pharmacophore scaffold has been shown to possess a range of activities as metal chelation, enzyme inhibition, cytotoxicity, and cytoprotection. Based on our previous findings we set out to optimize the scaffold for cytoprotective activity for its potential application in central nervous system related diseases. A 48-membered Betti-library was constructed by the utilization of formic acid mediated industrial-compatible coupling with sets of aromatic primary amines such as anilines, oxazoles, pyridines, and pyrimidines, with (hetero)aromatic aldehydes and 8-hydroxiquinoline derivatives. After column chromatography and re-crystallization, the corresponding analogues were obtained in yields of 13?90%. The synthesized analogs were optimized with the utilization of a cytoprotection assay with chemically induced oxidative stress, and the most active compounds were further tested in orthogonal assays, a real time cell viability method, a fluorescence-activated cell sorting (FACS)-based assay measuring mitochondrial membrane potential changes, and gene expression analysis. The best candidates showed potent, nanomolar activity in all test systems and support the need for future studies in animal models of central nervous system (CNS) disorders.
