Abstract
1,4-Conjugate addition of ((chloromethyl)sulfonyl)benzenes to arylideneisoxazol-5-ones, followed by one-pot, N-selective trapping in the presence of electrophiles, was investigated. This strategy led to the synthesis of new, stable N-protected isoxazol-5-ones in good yields and high diastereolectivity. The study of the reactivity of obtained products in the presence of the Mo(CO)6/H2O system allowed the development of a cascade reaction leading to novel methyl ketones in high yields and unchanged dr bearing an uncommon chloromethinearylsulfonyl end group.

Abstract
Eucalyptus plants have attracted the attention of researchers and environmentalists worldwide because they are a rapidly growing source of wood and a source of oil used for multiple purposes. The main and the most important oil component is 1,8-cineole (eucalyptol: 60–85%). This review summarizes the literature reported to date involving the use of 1,8-cineole for the treatment of disorders. Additionally, we describe our efforts in the use of eucalyptol as a solvent for the synthesis of O,S,N-heterocycles. Solvents used in chemistry are a fundamental element of the environmental performance of processes in corporate and academic laboratories. Their influence on costs, safety and health cannot be neglected. Green solvents such as bio-based systems hold considerable additional promise to reduce the environmental impact of organic chemistry. The first section outlines the process leading to our discovery of an unprecedented solvent and its validation in the first coupling reactions. This section continues with the description of its properties and characteristics and its reuse as reported in the various studies conducted. The second section highlights the use of eucalyptol in a series of coupling reactions (i.e., Suzuki–Miyaura, Sonogashira–Hagihara, Buchwald–Hartwig, Migita–Kosugi–Stille, Hiyama and cyanation) that form O,S,N-heterocycles. We describe the optimization process applied to reach the ideal conditions. We also show that eucalyptol can be a good alternative to build heterocycles that contain oxygen, sulfur and nitrogen. These studies allowed us to demonstrate the viability and potential that bio solvents can have in synthesis laboratories.

Abstract
An efficient synthesis of 4-arylidene-3-alkylisoxazole-5(4H)-ones has been implemented
via the three-component cyclocondensation of aryl(heteroaryl)aldehydes with hydroxylamine
hydrochloride and β-ketoesters. The potassium 2,5-dioxoimidazolidin-1-ide has
been introduced as the new organocatalyst to facilitate this heterocyclization. In the current
process, three starting materials, including substituted benzaldehydes/heterocyclic aromatic
aldehydes, hydroxylamine hydrochloride, and ethyl acetoacetate/propyl acetoacetate/butyryl
acetoacetate have been successfully used to synthesize the number of substituted isoxazole-
5(4H)-ones in good to high yields in ethylene glycol as a green reaction medium at 80 ºC. The
low catalyst loading is also a main advantage over some reported catalysts.

Abstract
In this work, we describe the application of a synthetic enzyme (synzyme) as the catalyst to promote the multicomponent synthesis of isoxazol-5(4H)-one derivatives. The catalytic system could be used up to 15 times without any notable loss of its activity. Some derivatives showed fluorescence and their photophysical data were evaluated. The mechanism of the reaction was, for the first time, investigated and, among the three reaction pathway possibilities, only one was operating under the developed conditions. ESI-MS(/MS) allowed for both the simultaneous monitoring of the multicomponent reaction (MCR) and the proposition of a kinetic model to explain the transformation. The kinetic model pointed firmly to only one reaction pathway and helped to discard the other two possibilities. The antimicrobial abilities of all synthesized derivatives against Gram-positive and Gram-negative strains were also evaluated. The abilities of functional chromophores (fluorescent compounds) as live cell-imaging probes were verified and one of the multicomponent adducts could stain early endosomes selectively in bioimaging experiments.

Abstract
A one-pot three-component reaction promoted by choline chloride: zinc(II) chloride deepeutectic
solvent (ChCl-ZnCl2 DES) in an aqueous medium for the synthesis of several merocyanin
dyes based on isoxazol-5(4H)-ones is presented. This three-component approach is efficient, clean,
experimentally simple, convenient, safe, and environmentally friendly. This reaction was performed at
room temperature without using energy sources such as heat, microwave and ultrasound waves. Nonuse
of toxic solvents, available materials, one-vessel, no wasted reagents, simple preparation, and recyclability
of DES are other important points of this method that is significant from the perspective of
green chemistry.

Abstract
The solvents used in chemistry are a fundamental element of the environmental performance of processes in corporate and academic laboratories. Their influence on costs, health safety, and nature cannot be neglected. Quantitatively, solvents are the most abundant constituents of chemical transformations; therefore, acting on solvents and replacing standard solvents with safer products can have a great ecological impact. However, not all green solvents are suitable for the wide scope of organic chemistry reactions. A second point to consider is that 50% of pharmaceutical drugs are nitrogen heterocycles compounds. It therefore appeared important to provide an overview of the more ecological methodologies for synthesizing this class of compounds. In this review, all publications since 2000 that describe green reactions leading to the formation of nitrogen heterocycles using safe solvents were considered. We chose water, PEG, and bio-based solvents for their negligible toxicity. The synthesis of five-, six-, and seven-membered aromatic nitrogen heterocycles using green reactions reported in the literature to date is described.

Abstract
Background:
4-Arylmethylideneisoxazol-5(4H)-ones are a class of organic compounds
with a variety of applications in the agriculture, filter dyes, photonic devices, and pharmaceutical industries.
They are also used as synthetic precursors for the synthesis of other organic compounds. As
a result, efforts are being made to search new and available catalyst and green methods toward their
synthesis.
Objective:
The aim of this work is to investigate the catalytic activity of salicylic acid as an inexpensive,
easy to handle, and safe catalyst to synthesis of some derivatives of isoxazole-5(4H)-ones in
water medium.
Methods:
To aqueous solution of equal amounts of aryl/heteroaryl aldehydes, β-ketoesters, and hydroxylamine
hydrochloride; salicylic acid (15 mol%) was added and the reaction mixture was stirred
at room temperature for a specified periods. The precipitated product was filtered and washed with
water to obtain 3-substituted-4-arylmethylideneisoxazol-5(4H)-ones. The reaction conditions were
also optimized and extended to synthesis other isoxazol-5(4H)-ones.
Results:
The salicylic acid is found to possess acceptable catalytic activity for the promotion of
three-component cyclocondensation of aryl/heteroaryl aldehydes, β-ketoesters, and hydroxylamine
hydrochloride. The three-component reaction led to construction of 3-substituted-4-arylmethylideneisoxazol-
5(4H)-ones in good to high isolated reaction yields.
Conclusion:
The efficient and environmental friendliness procedure for the synthesis of isoxazol-
5(4H)-ones is introduced. The reaction also carried out smoothly in water as a cost-effective, simple,
green, and non-toxic solvent at room temperature without using heating, microwave, and ultrasound
sources.
