A new methodology for the synthesis of α-diketones was reported via a one-pot cascade process from aldehydes and ketones catalyzed by a bifunctional iron nanocompositeusing H2O2 as a green oxidant in water. The one-pot strategy showed excellent catalytic stability, comprehensive suitability of substrates and important practical utility for directly synthesizing biologically active and medicinally
据报道,通过双锅铁纳米复合物在水中使用H 2 O 2作为绿色氧化剂,通过醛和酮的一锅级联过程,合成了一种合成α-二酮的新方法。一锅法显示出优异的催化稳定性,底物的全面适用性和重要的实际实用性,可通过间歇过程直接合成具有生物活性和医学价值的N-杂环。

From an initial lead 1, a structure-based design approach led to identification of a novel, high-affinity iminohydantoin BACE1 inhibitor that lowers CNS-derived Ab following oral administration to rats. Herein we report SAR development in the S3 and F' subsites of BACE1 for this series, the synthetic approaches employed in this effort, and in vivo data for the optimized compound.
