Description

General description

Complexation of the amino- and carboxyl-protected tripeptide with 3-amino-5-methylpyrazole was studied by low-temperature NMR experiments in a freonic solvent.

Application

3-Amino-5-methylpyrazole was employed as beta-sheet template to investigate its interaction with ferrocenoyl-dipeptides. It was also used in the synthesis of 4-aryl-3,7,7-trimethyl-2,4,6,7,8,9-hexahydropyrazolo[3,4-b]quinolin-5-ones.

Packaging
