An asymmetric synthesis of N-benzyl-D-aspartic acid

Abstract: An asymmetric synthesis of N-benzyl-D-aspartic acid was achieved by addition of benzylarnine to N-D-cr-methylbenzylmaleamic acid and hydrolysis of the resulting N1-benzyl-N2-D-cr-methylbenzylasparagine with 48% hydrobromic acid. Attempts to carry out asymmetric syntheses from crotonic or maleic acids and asymmetric bases were unsuccessful.

“…In der Literatur sind derartige Additionen vom asymmetrischen Michael-Typ mehrfach beschrieben worden. So wurde die Addition von (S)-Phenethylamin an Maleinsa Èure [11,12] und von (R)-und (S)-Phenethylamin an Malein-und Fumarsa Èurediethylester [13] bzw. -dimethylester [14] untersucht.…”
