  9. 4-Methylbenzhydryl-Resins - the Better Wang-Resin alternative

    Wang resins are widely used for peptide synthesis. However, certain side reactions, like diketopiperazin formation limit their use. 4-Methylbenzhydryl resin needs more space and leaves less room for this type of side reactions. Standard “Wang-typical” Fmoc/tBu coupling protocols can be applied.
