Two novel biscrown ethers with rigid cis/trans ethylene linker were synthesized via Wittig reaction in high yield (about 80%). Their pure cisltrans-isomers were obtained by column chromatography separation. And their structure/configuration was confirmed by ^1H NMR,^ 13C NMR, ESI mass spectrum, elemental analysis and UV-vis speca'a. 相似文献

A novel 4-anilinoquinazoline dimer linked by a carbon-carbon bond in the C-7 position was synthesized via a one step Suzuki cross-coupling reaction. All structures of new compounds were characterized by 1H NMR, 13C NMR, and HRMS. The inhibition rate of the synthetic 4-anilinoquinazoline dimer 8 against epidermal growth factor receptor-tyrosine kinase enzymes (EGFR) in vitro was 44.4% at the concentration of 5.5 μmol/L. 相似文献
