Process for preparing an alpha-amino acid, the corresponding ester and amide. |
摘要 |
Process for preparing an alpha -amino acid having the general formula (1) of <CHEM> where R represents an aryl group or a substituted aryl, cycloalkyl or alkyl group, in which process glyoxylic acid, or a precursor or derivative thereof, is contacted in the presence of sulphamic acid with an unsaturated compound chosen from the group of aromatics, cycloalkenes and alkenes. By applying the process higher efficiencies are obtained. The acid obtained as reaction product can be esterified and amidated without prior isolation.
