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.

Die Zeit als Tatbestandsmerkmalas fount to give similar results with NHC. The possibility of enantiocontrol of this reaction was indicated by the use of chiral phosphine and binaphthyl-based chiral DMAP. Further investigation on developing an efficient enantioselective variant is currently in progress in this laboratory.

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
