Abstract
A process for the production of an optionally substituted parahydroxyphenyl-α-amino acid (II) **(See formula)** or an acylic salt or derivatives thereof, where R1 is a hydrogen atom or a lower acyl group and R2, R3 and R4 are each a hydrogen or halogen atom or a hydroxyl, lower alkoxy, lower alkyl or acid group optionally esterified carboxylic acid or R3 and R4 attached to the carbon atoms to which they are attached form a carbocyclic ring, at least one of the radicals R2, R3 or R4 being a hydrogen atom; the procedure of which is to react one mole of glyoxylic acid or a precursor thereof with at least 1.3 mol of a compound of the general formula (V) or a salt thereof **(See formula)** and at least 1.5 moles of ammonia and then optionally forming a free acid, a salt or an N-acylated or O, N-diacylated derivative thereof, by known methods.
