Buchwald Hartwig diversification of unprotected halotryptophans, halotryptophan containing tripeptides and the natural product barettin in aqueous conditions

The research leading to these results has received funding from the European Research Council under the European Union’s Seventh Framework Programme (FP7/2007-2013/ERC grant agreement no 614779 GenoChemetics (to R.J.M.G) P. Cárdenas received support from the European Union's Horizon 2020 research and innovation program through the SponGES project (grant agreement No. 679849).Blending synthetic chemistry and biology is synthetically powerful. To further enable this, compatible synthetic tools are needed. We report the first Buchwald Hartwig amination reactions with unprotected halotryptophans in aqueous systems and demonstrate this methodology applicable to the modification of unprotected halotryptophans, simple tripeptides and the natural product barettin.Publisher PDFPeer reviewe
