The Dipicolylamino Group As an Efficient Leaving Group for Amide Bond Formation Via Hexafluoroisopropyl Ester.
Organic & biomolecular chemistry(2024)
摘要
Peptide dipicolylamide was prepared by the solid-phase method. The amide was activated by Cu(II) ions in hexafluoroisopropanol and converted to the corresponding active ester. It was condensed with the C-terminal segment to realize segment coupling. The method was successfully applied to the synthesis of an atrial natriuretic peptide and RNase T1.
