CAS 6456-74-2: Glycine tert-butyl ester

DL-Glycine tert-butyl ester

Glycine tert-butyl ester is used in the preparation of Schiff base by reacting with benzophenone. The resultant Schiff base undergoes asymmetric alkylation with arylmethyl bromides in the presence of O-allyl-N-(9-anthracenylmethyl)cinchonidinium bromide as chiral phase transfer catalyst to give guanidine-containing pentacyclic compound. This Thermo Scientific Chemicals brand product was originally part of the Alfa Aesar product portfolio. Some documentation and label information may refer to the legacy brand. The original Alfa Aesar product / item code or SKU reference has not changed as a part of the brand transition to Thermo Scientific Chemicals.

tert-Butyl glycinate is a synthetic reagent that contains a tert-butyl group. It is used in analytical chemistry to determine the concentrations of cinchonidine and ester hydrochloride in the reaction solution. This can be done by adding trifluoroacetic acid to the reaction solution, which causes the formation of tert-butyl glycinate. The hydrogen chloride from this reaction will react with sodium carbonate, forming hydrogen gas and sodium bicarbonate. The presence of nitrogen atoms on the tert-butyl glycinate molecule allows for an asymmetric synthesis, which can be used to synthesize serine protease.
