1,2,4-Triazolium phenacylides generated in situ from the corresponding 1,2,4- triazoliumsalts reacted with cinnamic esters to afford tetrahydropyrroiotriazoie derivatives. These [3+2] dipolar cycloaddition reactions occur stereo- and regiospecific, giving only derivatives of the type (4a-d). The stereo- and regiochemistry of these products was mainly elucidated by 1H-NMR, 13C-NMR and DEPT analysis.
