highly enantioselective and diastereoselective protocol for performing Mannichreactions has been developed by using a p-dodecylphenylsulfonamide-based proline catalyst. This catalyst facilitates the use of common, nonpolar solvents and increased concentrations as compared to alternative methods. A series of syn-selective Mannichreactions is reported, including the rapid access of α- and β-amino acids surrogates
