Abstract
Tetrabutylammonium fluoride catalytically induced a regioselective 1,3-cycloaddition of the carbanions leading to 2,2,4-substituted pyrrolidines. And in the presence of trifluoroacetic acid, the corresponding 2,2,3-substituted products were regioselectively obtained via the intermediary azomethine ylide.
