S. Kojo et K. Tanaka, Enantioselective crystallization of D,L-amino acids induced by spontaneousasymmetric resolution of D,L-asparagine, CHEM COMMUN, (19), 2001, pp. 1980-1981
Racemic D,L-asparagine induced spontaneous asymmetric resolution of co-exis
ting D,L-phenylalanine or D,L-tryptophan by recrystallization. from a homog
eneous aqueous solution, and the enantiomeric excess of phenylalanine or tr
yptophan in the resulting crystals correlated linearly with that of asparag
ine crystallized with phenylalanine or tryptophan.
