- Self-assembly and mechanism of L-Alanine-based dihydrazide derivative as excellent gelator of organic solvents
-
A new organogelator, L-Alanine dihydrazide derivative can self-assemble in various organic solvents and turned them into thermally reversible physical supramolecular organogels at extremely low concentrations ( 2 wt %). The gel-sol phase transition tempe

- A favorable, narrow, δh Hansen-parameter domain for gelation of low-molecular-weight amino acid derivatives
-
In recent years, the design of new low-molecular-weight gelators (LMWGs) has attracted considerable attention because of the interesting supramolecular architectures as well as industrial applications. In this context, the role of the organic solvent in d

- New system for peptide synthesis using N-acylpyrazoles
-
New system of peptide synthesis was described. The extension of one amino acid unit on the peptide chain was constituted from only 2 reaction steps, the conversion from esters to the corresponding N-acylpyrazoles and the subsequent aminolysis with amino esters. This new system was distinctive from the conventional peptide synthesis, which was consisted of 3 steps of the deprotection, the activation and the condensation. Moreover, the key intermediate N-acylpyrazoles exhibited the excellent properties of high sensitivity and separability for the chiral column on HPLC using the UV detector.
