A new method for the synthesis of protected
Nα-(Ï-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 allow for their incorporation
into peptides by solid phase peptide synthesis.
