该中间体在本合成路线中的序号：(II)The protected diaminopropionic acid building block (III) was prepared as follows. Rearrangement of N-Fmoc-L-asparragine (I) upon treatment with bis(trifluoroacetoxy)phenyliodine afforded the Fmoc-diaminopropionic acid (II), which was subsequently protected at the 3-amino group with di-tert-butyl dicarbonate.
