Abstract
The stereoselective synthesis of a new classes of boronato- or trifluoroborato aminoacids and peptides was described using Wittig and C-H iridium borylation as key reactions. A trifluoroborato-thiophene aminoacid derivative showed an excellent stability in aqueous conditions, useful for further applications as radiotracers by 18F labeling.
