Synthesis of novel biscrown ethers with rigid cis/trans ethylene bridge
摘要:
Two novel biscrown ethers with rigid cisltrans ethylene linker were synthesized v/a Wittig reaction in high yield (about 80%).Their pure cis/trans-isomers were obtained by column chromatography separation. And their structure/configuration was confirmedby 1H NMR, 13C NMR, ESI mass spectrum, elemental analysis and UV-vis spectra.
