In 1976,Journal of the Chemical Society included an article by Clark, John C.; Phillipps, Gordon H.; Steer, Margaret R.; Stephenson, Leslie; Cooksey, A. Roy. Recommanded Product: H-Phg-OEt.HCl. The article was titled 《Resolution of esters of phenylglycine with (+)-tartaric acid》. The information in the text is summarized as follows:
The Me, Et, and iso-Pr esters of DL-PhCH(NH2)CO2H were resolved with 1 mol. equivalent of (+)-tartaric acid in aqueous alcs. to give 25-42% D-ester hydrogen (+)-tartrate salts. The L-salts in the filtrates from the resolutions were racemized in EtOH containing polar cosolvents. The resolution and racemization stages can be combined so that DL-PhCH(NH2)CO2Et underwent a second order asymmetric transformation to give 65% Et D-phenylglycinate hydrogen (+)-tartrate. The resolved salts were hydrolyzed to give 66-91% D-PhCH(NH2)CO2H. In the experiment, the researchers used H-Phg-OEt.HCl(cas: 59410-82-1Recommanded Product: H-Phg-OEt.HCl)
H-Phg-OEt.HCl(cas: 59410-82-1) belongs to esters. They are important in biology, being one of the main classes of lipids and comprising the bulk of animal fats and vegetable oils.Recommanded Product: H-Phg-OEt.HCl Polyesters are important plastics, with monomers linked by ester moieties.
