what is of tert-Butyl glycinate with CAS 6456-74-2?
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.
