Abstract
Condensation of methyl-substituted six-membered heteroaromatics containing one or two nitrogen atoms with aldehyde derived from benzo-15-crown-5 ether in DMF in the presence of ButOK afforded 15-crown-5-containing hetarylphenylethenes. According to the results of NMR spectroscopy, these compounds exist as mixtures of syn and anti conformers in solution (MeCN-d3). The structures of two compounds were established by X-ray diffraction analysis.
