Gs. Currie et al., Chirally templated boronic acid Mannich reaction in the synthesis of optically active alpha-amino acids, J CHEM S P1, (17), 2000, pp. 2982-2990
Adducts from diastereoselective Mannich-type reactions of aldehydes, 2-fury
lboronic acid and the chiral amine template (S)-5-phenylmorpholin-2-one, ha
ve been used in the synthesis of a series of enantiomerically pure D-alpha-
amino acids.
