General description

Orthogonally-protected building block for the synthesis of head-to-tail cyclic peptides [1,2] 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[3], thereby facilitating the synthesis of branched esters and amides, and lactones and lactams incorporating a glutamyl unit.
