An alternative synthesis of N5-Acetyl-N5-hydroxy-L-ornithine from L-Ornithine
Milewska,Chimiak
, p. 233 - 234 (1990)
N5-Acetyl-N5-hydroxy-L-ornithine is obtained from L-ornithine in 20% overall yield via oxidation of the ω-amino group in N2-benzyloxycarbonyl-L-ornithine tert-butyl ester with dibenzoyl peroxide and subsequent N5-acetylation.
