The azido group can be reduced to an amino function and hereby serve as masked amino group. It is of particular use if additional orthogonalities are needed. Azido is stable towards treatment with piperidine (Fmoc deprotection), Pd(0) (Alloc removal) and acidic treatmet (cleavage of Mtt, Trt or other acid sensitive groups). However, as it is a pseudohalogenide, care has to be taken during coupling steps, as HATU will cause high racemization. This can be avoided using collidine or other non-nucleophilic bas...
