Rapid assembly of polycyclic structures via sigmatropic rearrangement of s-propargyl xanthates
Résumé
Upon heating in chlorobenzene, propargyl xanthates yield the corresponding 4,5-bis(alkylidene)-1,3-dithiolan-2-ones which are trapped by unactivated olefins in an intramolecular Diels-Alder cycloaddition yielding interesting polycyclic structures.
