Cinnamaldehyde derivatives were synthesized in good to excellent yields in one step by a mild and selective, base-free palladium(II)-catalyzed oxidative Heck reaction starting from acrolein and various arylboronic acids. Prepared α,β-unsaturated aldehydes were used for synthesis of novel α-aryl substituted fosmidomycin analogues, which were evaluated for their inhibition of Mycobacterium tuberculosis
从丙烯醛和各种芳基硼酸开始,通过温和且选择性的、无碱钯 (II) 催化的氧化 Heck 反应,一步合成肉桂醛衍生物,收率良好至极好。制备α,β不饱和醛被用于新的α -芳基膦胺霉素的类似物取代,将其评价它们的抑制的合成结核分枝杆菌1脱氧d -xylulose -5-磷酸还原。测量了介于 0.8 和 27.3 μM 之间的IC 50值。最好的化合物显示出与先前报道的最有效的 α-芳基取代的磷米霉素类抑制剂相当的活性。
