Sodium salts of ethyl N,N-dimethyl- and N,N-dimethylamidophosphoric acids I and II were obtained and their hydrolysis to respective acids was investigated. The salts and acids were characterized by spectral methods (MS, FT/IR, 1H, 13C, 31P NMR).
Ethyl (1S,2RS)-2-(2-chloropropanoyloxy)propanoate ((1S,2RS)-(I)) was obtained from rac-2-chloropropionyl chloride and ethyl L-lactate. (1S,2S)- (I) was also synthesized from (S)-2-chloropropionyl chloride and ethyl L-lactate with 93% d.e. (I) was undertaken hydrolysis by different media: NaOH/THF-H2O, Na2CO3/THF-H2O, LiOHxH2O/THF-H2O, 25% NaOH/H2O, and weakly acidic ion-exchange resin Amberlite IRC748...
