Oxa- and Azacycle-Formation via Migrative Cyclization of Sulfonylalkynol and Sulfonylalkynamide,ompanied 1,2-migration of the sulfonyl groups. This reaction provides a novel access to oxa- and azacycles possessing a pendant vinyl sulfone functionality, which in turn is amenable to further transformations. During research on this migrative cyclization, mechanism studies indicated that nucleophi

Oxa- and Azacycle-Formation via Migrative Cyclization of Sulfonylalkynol and Sulfonylalkynamide,les other than NHCs might also induce this transformation. Further investigations showed that a catalytic amount of phosphine or 4-(.-dimethylamino)pyridine (DMAP) also promoted migrative cyclization in an a. Umpolung manner similarly. Furthermore, asymmetric induction was observed when a chiral DMAP derivative was used in the reaction.
