-
Paragraph 0022-0033; 0041-0043, (2020/02/14)
The invention provides an N-benzyl glycine ethyl ester preparation and purification method, which comprises: preparing a N-benzyl glycine ethyl ester hydrochloride, wherein benzylamine and halogenatedethyl acetate are taken, and are subjected to a room temperature stirring reaction in an organic solvent, water is added after the HPLC detection results show that the reaction is completed, extracting is performed, an organic mixed solution of hydrochloric acid is added into the organic layer in a dropwise manner, the pH value is adjusted to 1-2, the solid is precipitated, and filtering and drying are performed; and adding water into the N-benzyl glycine ethyl ester hydrochloride, carrying out stirring dissolving, adjusting the pH value to 7-8 by using an alkali, adding an organic solvent, extracting, drying the organic layer by using anhydrous sodium sulfate, filtering, and carrying out pressure reducing concentrating to achieve a dry state so as to obtain the product N-benzyl glycine ethyl ester hydrochloride. The preparation method of the invention is simple in process operation, high in product yield, high in product purity and easy for industrial production.
Structure-property relationship study of n-(hydroxy)peptides for the design of self-assembled parallel β-sheets

The design of novel and functional biomimetic foldamers remains a major challenge in creating mimics of native protein structures. Herein, we report the stabilization of a remarkably short β-sheet by incorporating N-(hydroxy)glycine (Hyg) residues into the backbone of peptides. These peptide- peptoid hybrids form unique parallel β-sheet structures by selfassembly upon hydrogenation. Our spectroscopic and crystallographic data suggest that the local conformational perturbations induced by N-(hydroxy)amides are outweighed by a network of strong interstrand hydrogen bonds.
