Ring-closing enyne metathesis (RCEYM) for the synthesis of cyclic sulfoximines

Füger, Bernhard,Bolm, Carsten

, p. 1601 - 1604 (2009)

Heterocyclic sulfoximines have been synthesized by RCEYM reactions starting from N-alkynyl-S-alkenyl sulfoximines in up to 79% yield. The products can be converted to tricyclic derivatives by a domino Diels-Alder/aromatization reaction sequence. Georg Thi
