Quantitative Synthesis ofLOrDN2-Tertbutoxycarbonyl- 2,3-DIAMINOPROPANOIC ACID FROM PROTECTEDLORDSERINE-β -LACTONE

Abstract
The reaction of ammonia on protected L or D serine-β-lactone was reinvestigated. An easy synthesis of N2 -tertbutoxycarbonyl-L-2,3-diaminopropanoic acid (and D enantiomer). an important precursor of several antibiotics is proposed.
