摘要

[[9-[(9-Fluorenylmethyloxycarbonyl) amino] xanthen-2 (or 3)-yl] oxy] alkanoic acid (XAL) handles have been prepared by efficient four-step routes from 2-or 3-hydroxyxanthone and coupled onto a range of amino-functionalized supports. The resultant XAL supports are the starting points for solid-phase peptide synthesis by Fmoc chemistry. Upon completion of chain assembly, C-terminal peptide amides are released in excellent yields and purities ...
