✦ Synopsis

Tandem Radical Cyclizations Leading to Indolizidinones and Pyrrolizidinones.

-Depending on the alkene substituent, dehydroamino esters (I), (III), and (V) undergo 5-endo-5-exo or 5-endo-6-endo tandem cyclization under radical conditions with tin hydrides. Bicyclic products having potential application in pyrrolizidine and indolizidine alkaloid synthesis are obtained. -(BAKER,
