HCID 59540170(2S,3R)-3-methoxy-2-(methoxycarbonylamino)butanoic acid

Procedure

(2S,3R)-3-methoxy-2-(methoxycarbonylamino)butanoic acid was synthesized similar to N-methoxycarbonyl-L-Valine, using O-Methyl-L-Threonine instead of L-Valine. Dichloromethane extraction was carried out 10 times instead of 3 times.
