Description

General description

An excellent derivative for Fmoc SPPS of Arg-containing peptides ^[1]. Coupling of this derivative can be effected using standard activation methods, such as PyBOP^® or TBTU, although longer reaction times may be necessary due to the bulkiness of the side-chain protection.
