Agmatine and hirudonine, guanidine derivatives of putrescine and sperm
idine, respectively, are synthesised by the application of a new prote
cting group strategy for polyamines, which uses N-nitroguanidinyl as a
precursor of guanidine functions and selectively blocks spermidine at
N-1 and N-8 with trifluoroacetyl and at N-4 by 4-azidobenzyloxycarbon
