Tam, James P.,DiMarchi, Richard D.,Merrifield, R. B.
, p. 2851 - 2854 (1981)
Peptides with C-terminal α-carboxamides were synthesized from a multi-detachable benzhydrylamine-resin containing a Boc-(4-acetoxy)benzhydrylamine handle of unambiguous origin.The peptides bound to the new resin are stable to trifluoroacetic acid, but are cleavable by hydrogen fluoride, base and nucleophiles to give unprotected or protected peptide fragments.

HEMIAMINAL-TAG FOR PROTEIN LABELING AND PURIFICATION
-
Page/Page column 22; 23, (2018/06/30)
The invention pertains to the synthesis, isolation, and characterization of hemiaminal for selective labeling of peptides, proteins, antibodies, and organic fragments with -C(=0) CH2NH2 and derivatives with -CH2NH2 group over -C(=0) CHRNH2 group (where R≠H). The invention also pertains to the method of single-site immobilization of proteins through N-terminus Gly on solid phase. The invention includes late-stage tagging of N-terminus Gly with an affinity tag, 19F NMR probe, and a fluorophore and a method for metal-free protein purification and isolation of analytically pure proteins.

Paragraph 0048; 0049; 0050; 0051; 0052, (2018/01/11)
The invention provides a synthetic method for chiral alpha-aminoamide compounds, belongs to the technical field of organic synthetic methodology, and concretely relates to a synthetic method for chiral alpha-aminoamide compounds, wherein the method has a simple process, low costs and good economy. The method comprises the following steps: 1, performing ammonolysis: adding substituted chiral alpha-aminocarboxylate hydrochloride into concentrated ammonia water, performing stirring for 4-12h under a room temperature, wherein each 1mmol substituted chiral alpha-aminocarboxylate hydrochloride is corresponding to 2-8mL the concentrated ammonia water; 2, after a reaction is finished, performing distillation for removing ammonia water after the reaction to obtain crude products chiral alpha-aminoamide compounds; and 3, performing filtration on the obtained crude products chiral alpha-aminoamide compounds by adopting a manner of adding a solvent or performing purification on the obtained crude products chiral alpha-aminoamide compounds through a manner of column chromatography which uses ammonia water as a mobile phase to obtain the products chiral alpha-aminoamide compounds. Compared with the prior art, a large number of an ammonia gas for ammonolysis is not needed in the method, the process and post-treatment are simple, costs are low and reaction time is short.
