Proline-catalysed asymmetric amination of alpha,alpha-disubstituted aldehydes: synthesis of configurationally stable enantioenriched alpha-aminoaldehydes.
Proline-catalysed amination of alpha,alpha-disubstituted racemic aldehydes with azodicarboxylates proceeds smoothly to give configurationally stable scalemic aldehydes and oxazolidinones in up to 86% ee.
