naturally abundant aldehydes, as both alkylation reagents and hydrogen donors. The hydroalkylation proceeds with high regio‐ and stereoselectivity to form (Z )‐alkenes, which are more difficult to generate compared to (E )‐alkenes. The reaction is compatible with a wide range of functional groups, including hydroxy, ester, ketone, nitrile, boronic ester, amine, and halide groups. Furthermore, late‐stage modifications
我们已经开发了前所未有的钯催化炔与with的正式加氢烷基化反应,是由自然丰富的醛作为烷基化试剂和氢供体原位生成的。加氢烷基化以较高的区域选择性和立体选择性进行,形成(Z)烯烃,与(E)烯烃相比更难以生成。该反应与各种官能团相容,包括羟基,酯基,酮基,腈基,硼酸酯基,胺基和卤基。此外,天然产物和药物衍生物的后期修饰体现了其独特的化学选择性,区域选择性和合成适用性。机理研究表明,钯氢化物中间体可能参与其中。
