Insoluble polymer supports as monoblocking agents of symmetrical diamines

Abstract

Benzoylation of monoprotected polymer-bound symmetrical aliphatic diamines at the free amino end and cleavage with trifluoroacetic acid yields the unsymmetrical diamides, CF₃CONH[CH₂]_nNHCOPh, where n= 4, 6, 8, 10, or 12.
