Descripción

General description

Orthogonally-protected building block for the synthesis of branched and cyclic peptides and peptides modified at the Lys side chain by Fmoc SPPS. The Alloc group can be selectively removed in the presence of standard Fmoc- and t-butyl-based protecting groups by treatment with Pd(Ph₃P)₄/CHCl₃/AcOH/NMM.
