Electrophilic olefin heterocyclization in organic synthesis. Stereoselective synthesis of 4,5-disubstituted .gamma.-lactams by iodine-induced lactam formation of .gamma.,.delta.-unsaturated thioimidates
The novel and efficient approach toward the synthesis of endocyclic enol lactones was devised based on ring-closing metathesis of unsaturated carboxylic acids vinyl esters. Systematic studies revealed that vinyl esters are suitable substrates for RCM reaction. The developed methodology offers an easy route for synthetically challenging target molecules with different functionalgroups and substitution
