Abstract

A new method for the synthesis of protected Nα-(ω-Y-alkyl) amino acids (Y is a thio, amino or carboxy group) and related compounds by reductive alkylation of natural amino acids is reported. These new amino acids serve as building units for the synthesis of backbone- cyclic peptides. They are orthogonally protected at the α-amino position by butoxycarbonyl (Boc) or 9-fluorenylmethoxycarbonyl (Fmoc), using trimethylsilyl temporary protection, to ...
