General description

Orthogonally-protected building block for the synthesis of head-to-tail cyclic peptides [1,2,3,4,5] by Fmoc SPPS. The α-allyl ester can be selectively removed in the presence of Fmoc- and tBu-based protecting groups by treatment with Pd(Ph3P)4/ CHCl3/AcOH/NMM [6], thereby facilitating the synthesis of branched esters, amides, lactones and lactams incorporating an aspartyl unit.
