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.

Fluorinated isoxazolines and isoxazoles: A synthetic perspective

Isoxazoline and isoxazole derivatives are an important class of nitrogen and oxygen containing heterocycles that are well known to display an array of various biological properties. Among them, compounds bearing fluorine or fluoroalkyl substituents not only exhibit important pharmacological and agrochemical properties but also act as useful precursors for the synthesis of some biologically potent agents. In addition, mechanistic aspects leading to their formation and NMR spectral characteristics have been a matter of great interest to the synthetic and medicinal chemists. Therefore, this review summarizes the overall developments made on the syntheses of fluorinated isoxazoline and isoxazole derivatives till date besides their biological importance.

Reactions of an imidazo[4,5-c]isoxazole-6-carboxylate with electron deficient acetylenes

The synthesis of the first examples of the imidazo[4,5-c]isoxazole ring system has recently been reported,(2) but little is known about the chemistry of this heterocycle. In this paper we describe our investigation into the behaviour of an imidazo[4,5-c]isoxazole-6-carboxylate ester with acetylenic esters and ketones. A complex reaction sequence is found to occur, involving addition of two molecules of alkyne followed by ring opening and fragmentation, leading to the formation of 2-pyrrol-2-yl imidazoles in moderate yield. The mechanism and scope of the reaction is discussed. (C) 1999 Elsevier Science Ltd. All rights reserved.
