WebDbz resins as supplied contain mostly 3-Fmoc-Dbz, with small amounts of 4-Fmoc-Dbz and bis-Fmoc-Dbz. Capping the resin with Alloc-Cl prior to removal of the Fmoc group will thus reduce the maximum potential for branching or truncation to 6%. For hindered amino acids, it has been found necessary to load the resin prior to capping with Alloc.
