A short synthesis of a novel Fmoc-derivative 2b of the phosphonic acid isostere 1 of aspartic acid is presented. Incorporation of 2b into peptides was readily achieved using standard Fmoc-solid phase synthesis. Efficient removal of the allyl protecting groups after sequence assembly under mild conditions using Pd(0) catalysis afforded phosphonopeptides 3a and 3b in high purity.
