Method for continuously and quickly preparing DL-phenylglycine and analogue thereof

The invention provides a method for continuously and quickly preparing DL-phenylglycine and an analogue thereof. The method comprises the steps of adding 2-hydroxyl-phenylacetonitrile and an analoguethereof (cyanohydrin for short) and an aqueous ammonium bicarbonate solution into a microchannel reactor for a reaction, controlling the reaction temperature to be 80-130 DEG C, and controlling the reaction pressure to be 0.5-2.0 MPa, wherein the standing time of the reactants in a microchannel is 1-8 min, and an aqueous solution of 5-phenyl-hydantoin and an analogue thereof (hydantoin for short)is obtained; adding the hydantoin and alkali into the microchannel reactor for a reaction, controlling the reaction temperature to be 120-200 DEG C, and controlling the reaction pressure to be 1.0-3.5MPa, wherein the standing time of the reactants in the microchannel is 1-8 min, and then a saline solution of phenylglycine and an analogue thereof is obtained; conducting acidification neutralization and crystallization to obtain the phenylglycine and the analogue thereof. According to the method, the microchannel reactor is adopted, the reaction time is greatly shorted, the reaction speed is increased, pyrolysis and polymerization of the cyanohydrin are reduced, no by-products are generated, the products are high in yield, clean and environmentally friendly, and the production cost is lowered.

Process for preparation of 2-chlorophenylglycine derivatives and enantiomerically separation

The present invention relates to novel processes and intermediates for the preparation of R(?)-α-2-chlorophenylglycine, S(+)-α-2-chlorophenylglycine, and RS-2-chlorophenylglycine derivatives of formulas I, II and III, respectively. The resulting enantioseparative system was validated in order to evaluate the presence of the enantiomer in pharmaceutical samples.
