- Convenient Synthesis of O-(2-Acetamido-2-deoxy-β-D-glucopyranosyl)-serine and -threonine Building Blocks for Solid-phase Glycopeptide Assembly
-
The suitably protected building blocks for solid-phase glycopeptide synthesis, Nα-Fmoc-Ser(Ac3-β-D-GlcNAc)-OPfp, 11, and Nα-Fmoc-Thr(Ac3-β-D-GlcNAc)-OPfp, 12, have been synthesized by stereoselective glycosidation of the 2-allyloxycarbonylamino glycosyl donor 7 with Nα-Fmoc-Ser-OPfp, 3, and Nα-Fmoc-Thr-OPfp, 4, followed by Pd0-catalysed allyl transfer from the N-allyloxycarbonyl group in the presence of acetic anhydride.

- 9-Fluorenylmethyl Pentafluorophenyl Carbonate as a Useful Reagent for the Preparation of N-9-Fluorenylmethyloxycarbonylamino Acids and their Pentafluorophenyl Esters
-
9-Fluorenylmethyl pentafluorophenyl carbonate is a useful reagent for the efficient, side reaction-free introduction of N-9-fluorenylmethyloxycarbonyl protecting group into amino acids and for the subsequent preparation of their pentafluorophenyl esters.Some new compounds of both types are described.
