摘要

The acid-labile 5444 9-fluorenylmethyloxycarbonyl) aminomethyl-3, 5-dimethoxyphenoxy) valeric acid (PAL) handle 1 is described for the solid-phase synthesis of C-terminal peptide amides. The pure para isomer of 1 was prepared by each of two efficient five-step routes, in overall yields from 52% to 74%. The handle 1 was coupled onto a variety of amino group- containing supports to provide a general starting point for stepwise assembly of peptide ...
