The synthesis of fungicidal aminophosphonic acid derivatives
Published 1988“…The use of Fast Atom Bombardment mass spectrometry has proven to be successful for the characterisation of aminophosphonic acid derivatives, especially phosphonopeptides, with the MH ion normally being the base peek. Phosphonopeptides give characteristic fragmentation patterns due to the sequential loss of [alpha]-lactam units arising from the amino acid chain. …”
