Transfer hydrogenative reductive amination of 5-(hydroxymethy)furfural (HMF) has been accomplished, catalysed by a cyclometalated iridium catalyst with formic acid as a hydrogen source. The catalytic system afforded a TON of 9600 and TOF of 14 400 h⁻¹, and the reaction can be successfully scaled up to a 10 gram scale at a substrate-to-catalyst ratio of 10 000. A wide range of amines could be coupled with HMF to afford furan derived products, including modified drug molecules, key intermediates for drug synthesis and potential monomers for polymer synthesis.

铱催化转移氢化高效还原胺化 5-羟甲基糠醛


以甲酸为氢源，在环金属铱催化剂的催化下，实现了5-(羟甲基)糠醛(HMF)的转移加氢还原胺化。该催化体系的TON为9600，TOF为14 400 h ^-1 ，并且在底物与催化剂的比例为10 000的情况下，反应可以成功放大至10克规模。可以偶联多种胺。与 HMF 一起生产呋喃衍生产品，包括修饰的药物分子、药物合成的关键中间体和聚合物合成的潜在单体。
