(2S)-2-(((tert-butoxy)carbonyl)amino)-3-methoxypropanoic acid → (2R)-3-methoxy-2-(methylamino)propanamide

Participants

Reaction Steps

N2,O-dimethyl-D-serinamide was prepared by methylating N-(tert-butoxycarbonyl)-O-methyl-D-serine using an analogous method to that described in Example 7 for the methylation of N-(tert-butoxycarbonyl)-O-methyl-L-serine, to give N-(tert-butoxycarbonyl)-N,O-dimethyl-D-serine; 1H NMR spectrum: (DMSO d6, 100° C.) 1.40 (s, 9H), 2.77 (s, 3H), 3.26 (s, 3H), 3.67 (m, 2H), 4.51 (m, 1H).
