Highlyenantioselective catalytic routes to Boc protected β-amino aldehydes, β-amino acids and γ-amino alcohols are presented. The organocatalytic asymmetric reactions between unmodified aldehydes and N-Boc protected aryl imines proceed with excellent chemo- and enantioselectivities to give the corresponding compounds in high yields with up to >19:1 dr and 93% to >99% ee.

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
One-pot highly enantioselective catalytic Mannich-type reactions between aldehydes and stable α-amido sulfones: asymmetric synthesis of β-amino aldehydes and β-amino acids
A highlyenantioselective catalytic route to carbamate- and benzoate-protected β-amino aldehydes and β-amino acids is presented. The amino acid-catalyzed one-pot asymmetric reaction between unmodified aldehydes and α-amido sulfones gives the corresponding β-amino compounds with up to 95:5 dr and 97–>99% ee.
