Abstract
The structure of the pentasubstituted pyridines obtained in the reacti on of methyl 2-isothiocyanato-3-phenylpropenoate with 1-(N,N-diethylam ine)prop-1-yne were assigned based on 2D heteronuclear correlation exp eriments and NOE measurements. At 0 degrees C a 2-azabicyclo[2.2.2] oc ta-2,7-diene intermediate was isolated and spectroscopically character ized.
