Method for preparing p-hydroxyphenylglycine in pulse tubular reactor

The invention discloses a method for preparing p-hydroxyphenylglycine in a pulse tubular reactor, which is characterized in that glyoxylic acid, phenol and sulfamic acid are used as raw materials, p-hydroxyphenylglycine is prepared in a novel pulse tubular reactor in a nitrogen atmosphere, and the method belongs to the technical field of organic synthesis processes. Materials are introduced into the pulse tubular reactor through a metering pump and then subjected to preheating, mixing reaction and separation to obtain a p-hydroxyphenylglycine product, and compared with a process reported in literatures, the novel process has the advantages that the reaction time can be greatly shortened, the workshop efficiency can be improved, the reaction temperature can be accurately controlled, and the generation of by-products can be effectively reduced. And by introducing the novel pulse reactor, the mass and heat transfer effect of the reaction is qualitatively improved compared with that of a kettle type process, so that the use of a phase transfer catalyst is avoided, and the cost is saved. Compared with methods reported in literatures, the process technology has the advantages that the glyoxylic acid conversion rate, the product selectivity and the like are remarkably improved, and the existing outdated process technology can be replaced after the process technology is put into production.

Synthesis of Unprotected 2-Arylglycines by Transamination of Arylglyoxylic Acids with 2-(2-Chlorophenyl)glycine

The transamination of α-keto acids with 2-phenylglycine is an effective methodology for directly synthesizing unprotected α-amino acids. However, the synthesis of 2-arylglycines by transamination is problematic because the corresponding products, 2-arylglycines, transaminate the starting arylglyoxylic acids. Herein, we demonstrate the use of commercially available l-2-(2-chlorophenyl)glycine as the nitrogen source in the transamination of arylglyoxylic acids, producing the corresponding 2-arylglycines without interference from the undesired self-transamination process.
