Abstract: It was found that nano-SiO2–H2SO4 was catalyzed by the three-component cyclocondensation of aryl/heteroaryl aldehydes, hydroxylamine hydrochloride, and β-ketoesters toward the synthesis of α,β-unsaturated?isoxazol-5(4H)-ones under green conditions. The reaction yielded the corresponding heterocycles at room temperature in relatively shorter reaction times. It merits mentioning that the mild conditions allow the synthesis of several α,β-unsaturated?isoxazol-5(4H)-ones using this method. In this study, some new derivatives of isoxazolones were also synthesized and characterized. It is efficient, clean, simple, safe, and ecologically friendly. This straightforward method is cost-effective and requires no preparation of reactants. The three-component annulation was performed without using energy sources, for example, heat, ultrasound wave, and microwave irradiation. Graphic abstract: [Figure not available: see fulltext.].

In the present work, the nanocrystalline particles of hydroxyapatite (HAp) using an easy alkoxide-based sol–gel technique including triethyl phosphate [PO (OC2H5)3] and Ca (NO3)2·4H2O as P and Ca precursors have been synthesized. The sample characterization was performed by X-ray diffraction, Fourier transform-infrared analysis, scanning electron microscopy, thermal analysis (thermogravimetric analysis/differential thermal analysis), and elemental analysis of energy-dispersive X-ray analysis. It is interesting that single phase of HAp was obtained at a low firing temperature of 500°C. Modified Scherrer equation as the Williamson?Hall method was applied for the measurement of crystallite size distributions and micro-strain of the sample. The determined crystallite size by complementary technique of transmission electron microscopy has good consistency with those obtained from the Scherrer formula. Moreover, we reported the one-pot synthesis of 3,4-disubstituted isoxazole-5(4H)-ones through the aqueous solution reaction of three components of ethyl acetoacetate, hydroxylamine hydrochloride and various aromatic aldehydes at room temperature. This protocol offers several advantages, including a simple work-up procedure, very short reaction times (under 25?min), in accordance with the principles of green chemistry, recyclability, excellent yields (87–98%) and environmentally friendly.
