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.

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
