Pipecolic Acid-Catalyzed Direct Asymmetric Mannich Reactions
[Image: see text] Mannich reactions between aldehydes and N-p-methoxyphenyl-protected α-imino ethyl glyoxylate have been performed using (S)-pipecolic acid as catalyst. The reactions give both syn- and anti-products (dr = 1.4–2:1) with high enantioselectivities (>98% ee). In contrast, (S)-proline...
