✦ Synopsis

Intramolecular Cycloaddition of 5-Alkenyl-1-pyrroline 1-Oxide-5carboxylic Esters.

-Thermal treatment of the pyrroline-1-oxides (Ia)-(Ic) results in intramolecular cyclization to give the azatricyclo compounds (II) and (III), while (Id) fails to react. The products are subjected to hydrogenolysis, forming azabicyclic derivatives and cyclic amino esters. -(BLACK, D.
