Received: 29 November 2010; in revised form: 14 December 2010 / Accepted: 15 December 2010 / Published: 20 December 2010 Abstract: A new class of 1,3,5-triazinyloxyimino derivatives were prepared, characterized and tested for reactivity in solution peptide synthesis. The new triazinyloxyimino derivatives failed to activate the carboxyl group during formation of peptide bonds, but
