3-trifluoromethanesulfonamido-Pyrrolidine: A general organocatalyst for antf-selective mannich reactions

Pouliquen, Mickael,Blanchet, Jerome,Lasne, Marie-Claire,Rouden, Jacques

supporting information; experimental part, p. 1029 - 1032 (2009/04/07)

Mannich-type reactions of a glyoxylate imine with carbonyl compounds catalyzed by 3-trifluoromethanesulfonamidopyrrolidine proceed with high yields and anfi-stereoselectivity. The catalyst is easily prepared and the transformation appears to be quite general accommodating aldehydes or ketones.
