Abstract
The structure of the cycloadducts from 2-cyano-trans-stilbene oxide with acetylenic and olefinic dipolarophiles confirm the electrocyclic C–C ring scission of the oxiran while the cycloadditions of 3 cyano-trans- and cis-stilbene oxide to dimethyl fumarate establish the conrotatory course.Keywords
