TRANSFORMATION OF cis-ENYNE-SUBSTITUTED OXIRANES TO 2-VINYLFURANS SEVEN-MEMBERED CYCLOALLENES AS INTERMEDIATES ?

Roser, Joachim,Eberbach, Wolfgang

, p. 2455 - 2458 (2007/10/02)

Upon thermal activation the 1,2-epoxy-(Z)-3-hexen-5-ynes 5a-c are transformed predominantly into the 2-vinylfurans 9a-c/10a-c.A reaction mechanism is proposed which involves the transformation of 7-membered cycloallenes (structure 3) as central intermediates.
