Isoxazole-azirine isomerization as a reactivity switch in the synthesis of heterocycles

This review contains a generalized and systematically arranged data about thermal, photochemical, and catalytic transformations of isoxazole-2-carbonyl-2H-azirine that were published in the period from 1969 to 2015, and considers the possibilities for using these compounds in the synthesis of nitrogen heterocycles. Radical and pericyclic steps of isomerization reactions have been discussed. Density functional theory calculations of the relative thermodynamic stability of isomeric isoxazoles and azirines have been performed. A total of 76 references are given.

Synthesis and biological activity of a novel class nicotinic acetylcholine receptors (nAChRs) ligands structurally related to anatoxin-a

The introduction of the isoxazole ring as bioisosteric replacement of the acetyl group of anatoxin-a led to a new series of derivatives binding to nicotinic acetylcholine receptors. Bulkier substitutions than methyl at the 3 position of isoxazole were shown to be detrimental for the activity. The binding potency of the most interesting compounds with alpha 1, alpha 7 and alpha 3 beta 4 receptor subtypes, was, anyway, only at micromolar level. Moreover, differently from known derivatives with pyridine, isoxazole condensed to azabicyclo ring led to no activity. (C) 2011 Elsevier Ltd. All rights reserved.

KI-Mediated Three-component Reaction of Hydroxylamine Hydrochloride with Aryl/Heteroaryl Aldehydes and Two beta-Oxoesters

A KI-mediated multi-component cyclocondensation of hydroxylamine hydrochloride, aromatic/hetero-aromatic aldehydes, and ethyl acetoacetate or 4-chloroethyl acetoacetate to form isoxazole-5(4H)-one heterocycles is described. The reaction employs readily accessible starting reactants and provides a range of synthetically isoxazole-5(4H)-ones in good to high yields. Reactions were performed in water as a green medium at room temperature (rt) without heating, microwave irradiation or sonication. Reusability of the reaction medium is also a noteworthy characteristic of this reaction.

Isoxazoline- and isoxazole-liquid crystalline schiff bases: A puzzling game dictated by entropy and enthalpy effects

Two series of Schiff base (SB) liquid crystals (LC) containing the 5-membered rings isoxazoline or isoxazole were synthesized and characterized; 27 isoxazoline and 20 isoxazole compounds were obtained. Nematic, smectic A, and smectic C mesophases were found and characterized by Polarized optical microscopy (POM), Differential scanning calorimetry (DSC), and X-ray diffraction. The scientific problem addressed was how the isoxazoline and isoxazole rings affect the mesophase structure and stability. Molecular packing and anisotropic interactions based on enthalpy and entropy properties were used to explain the thermal and structural behaviour observed for both series. The proposed mechanism was assisted by Density functional theory (DFT) calculations, providing new insights into the molecular organization of this kind of system. (C) 2019 Elsevier B.V.
