[摘要]:Some 2-(arylmethylthio)indolizines bearing ethoxycarbonyl and/or cyano group(s) at the 1- and 3-positions were synthesized and their conformations were investigated by H-1-NMR spectra and X-ray analyses. Interestingly, it was indicated that the sulfide linkages in 2-(1-naphthylmethylthio)indolizine derivatives in CDCl3 solution are mainly present in gauche conformations and the intramolecular arene-pi (cation) interactions reflect the electrophilic reactivity of the 1- and 3-substituents. |
