CA 2760071

There is provided a novel process for preparing polyamides (in particular cyclic and hairpin polyamides) comprising the step of coupling an amine with a Boc-protected amino acid monomer in the presence of diphosgene and/or triphosgene. Such a process may be performed on a solid or solution phase.

La présente invention concerne un nouveau procédé pour préparer des polyamides (en particulier des polyamides cycliques et en épingle) comprenant une étape consistant à coupler une amine à un monomère d'acide aminé à protection Boc en la présence de diphosgène et/ou de triphosgène. Un tel procédé peut être mis en oeuvre sur une phase solide ou une phase solution.
