Description

General description

An excellent derivative for the synthesis by Fmoc SPPS of branched peptides and peptides modified at the lysine side-chain ^[1], and for the construction of templates and multifunctionalized resins for combinatorial synthesis.The side-chain Mmt group can be selectively removed in the same manner as Mtt with 1% TFA in DCM ^[2,3,4] or DCM/HFIP/TFE/TES (6.5:2:1:0.5) ^[5]. Alternatively, it can be removed under milder conditions with AcOH/TFE/DCM (1:2:7) ^[1], leaving Mtt intact.
