Stereoselective synthesis of sulfonyl-substituted trans-2,3-dihydrofuran derivatives via reaction of arsonium Ylides with α,β-unsaturated ketones
Chemical Research in Chinese Universities - Tập 30 - Trang 596-600 - 2014
Trans-2,3-dihydrofuran derivatives 3 or 4 substituted with a sulfonyl group were prepared with high chemoselectivity and good yields by [1+4]-addition reaction of α,β-unsaturated ketones 1 with arsonium bromide 2 in CH2Cl2 in the presence of potassium carbonate at room temperature. The structures of the products were characterized by IR, MS, 1H NMR, elemental analysis and single c...... hiện toàn bộ

Research on Ice Crystal Growth Inside the Vitrified Vs55 with Magnetic Nanoparticles During Devitrification by Cryomicroscopy
Chemical Research in Chinese Universities - Tập 35 - Trang 542-548 - 2019
The effect of magnetic nanoparticles(mNPs) on the devitrification crystallization of typical vitrification solution Vs55 was systematically explored by differential scanning calorimetry(DSC) and cryomicroscope system. The results show that, (i) the mNPs coated by both carboxylic acid(CA) and polyethylene glycol(PEG) had little effect on the glass transition temperature(Tg) of Vs55, but had signifi...... hiện toàn bộ
Synthesis of P-Stereogenic Diarylphosphinamides as Novel Inhibitors of Melanoma
Chemical Research in Chinese Universities - Tập 35 - Trang 812-816 - 2019
In this paper, the evaluation on the biological activity of an array of P-stereogenic diaryphosphinamides as novel inhibitors of malignant melanoma was presented. Among 20 derivatives being screened, several of them displayed high inhibition rate up to 90% against the B16 melanoma cells at 100 μg/mL. Moreover, one of them displayed high inhibition activity with IC50 value of 5.8 μg/mL. In contrast...... hiện toàn bộ
Effect of Zr addition on catalytic performance of Cu-Zn-Al oxides for CO2 hydrogenation to methanol
Chemical Research in Chinese Universities - Tập 32 - Trang 1005-1009 - 2016
A series of 50%CuO-25%ZnO-25%Al(Zr) oxide catalysts was synthesized by a reverse co-precipitation method and characterized by XRD, N2 adsorption-desorption, H2-TPR, H2-TPD and CO2-TPD, and used as catalyst for CO2 hydrogenation to methanol under mild conditions(200―260 °C and 1―3 MPa). Consequently, H2-TPR ex-hibited that the dispersed CuO species increased with the zirconium content, while the H2...... hiện toàn bộ
