It has been found that N-trimethylsilylmethylamine reacts with unsymmetrical dipolarophiles to give 2,2,4- or 2,2,3-trisubstituted pyrrolidines in the presence of tetrabutylammonium fluoride or fluoroacetic acid, respect
HIGH REGIOSELECTIVITIES IN 1,3-CYCLOADDITION OF INTERMEDIARY CARBANIONS PROMOTED BY TETRABUTYLAMMONIUM FLUORIDE AND AZOMETHINE YLIDE CATALYZED BY TRIFLUOROACETIC ACID

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 regioselectivel
