using solution methods , we have synthesized several series of l-methionine homo-oligopeptides from the dipeptide to the hexapeptide with either a free alpha-carboxyl function or different c-blocking groups ( methoxy , benzyloxy , benzylamino ) and with n-blocking groups of either the amide type ( formyl , pivaloyl ) or the urethane type ( tert.-butyloxycarbonyl ) .
