This protocol describes a procedure for the synthesis of α, β-branched-b-amino aldehydes via Proline-catalyzed asymmetric Mannich reaction of aldehydes with N-tert–butoxycarbonyl-imines. The ...
DESPITE ITS VALUE as a nucleophile, the simple molecule acetaldehyde has long been considered too problematic to use in enantioselective reactions catalyzed by small molecules. Now, thanks to tweaking ...
