  Synthesis and spectroscopic investigation of some dimeric coumarin and furanocoumarin models

  摘要：

  The synthesis of some dimeric coumarin and furanocoumarin models and their structure elucidation by H-1 NMR, C-13 NMR, and mass spectroscopy is presented. In the presence of moisture some aldehydes are accompanied by their hydrates. Methoxy signal doubling in the presence of a chiral lanthanide shift reagent proves the dimeric nature of compound 8. In the mass spectra, heterolytic cleavage of the O-C linkage was noticed which is a ran fragmentation in the case of aromatic ethers.
