1 - -2-Amino-2-carboxy-ethyl

The first known 1-carboxyethyl ether of a sugar was 2-amino-3-0-[(/ )-l-carboxyethyl]-2-deoxy-D-glucose or muramic acid (37). It is a component of the polysaccharide moiety of the peptidoglycan in the bacterial cell-wall. It is partially replaced by the mamo isomer, 2-amino-3-6>-[(/ )-l-carboxy-ethyl]-2-deoxy-D-mannose, in the peptidoglycan from Micrococcus lyso-deikticus. [Pg.303]

This enzyme [EC 1.5.1.16], also referred to as D-lysopine synthase, catalyzes the reaction of iV -(D-l-carboxy-ethyl)-L-lysine with NADP+ and water to produce l-lysine, pyruvate, and NADPH. In the reverse reaction, a number of L-amino acids can serve as substrates instead of L-lysine. [Pg.435]

Bei einem anderen Verfahren zur Herstellung von optisch-aktiven Aminoalkanen aus Oxim-Derivaten reduziertman O-Alkyl-oxime, deren Alkyl-Gruppe (evtl. auch funktionell substituiert) mit einem asymmetrischen C-Atom an die Hydroximino-Gruppe gebunden ist1. Auf diese Weise erhalt man z.B. durch Reduktion von chiralem Acetophenon-[0-(l-carboxy-ethyl)-oxim] mit Boran-Tetrahydrofuran (S)-1-Amino-1-phenyl-ethan in 72% chemischer Ausbeute und einem ee-Wert von 40%.

Die Herstellung von Phosphinsauren aus Phosphonigsaure-diestern ist auch durch Addition der Letzteren an aktivierte C=C-Bindungen und Verseifung der primaren Reak-tionsprodukte moglich. Auf diese Weise ist z. B. (2-Amino-2-carboxy-ethyl)-methyl-phos-phinsaure aus Diethoxy-methyl-phosphan mit 2-Acetylamino-acrylsaure zuganglich68. [Pg.134]
