A semi-rigid, tetradentate, bifunctional chelator (BFC) for the oxorhenium core has been synthesised in five steps with an overall yield of 46 %. An aromatic amine is available for conjugation to a peptide through an isothiocyanate function. This BFC is the first amine-functionalised tetradentate ligand containing both amido and thiol functionalities. Monooxorhenium complexes were readily prepared
用于氧铼核心的半刚性、四齿双功能螯合剂 (BFC) 已通过五个步骤合成,总产率为 46%。芳香胺可通过异硫氰酸酯功能与肽结合。该 BFC 是第一个包含酰胺基和硫醇官能团的胺官能化四齿配体。Monooxorhenium 配合物很容易从双功能螯合剂和 β-丙氨酸-共轭系统制备。这些复合物以良好的收率获得并且被充分表征。此外,发现它们对配体交换反应稳定。 (© Wiley-VCH Verlag GmbH & Co. KGaA, 69451 Weinheim, Germany, 2006)
