A new strategy for the assembly of himbacine and analogues, which display potent biological activity, is described. A four-step route to a key intermediate has been developed, in which the key step is a highly diastereoselective Michael-Dieckmann domino reaction. Use of an enantioenriched Michael acceptor, readily obtained by an asymmetric dihydroxylation reaction, allowed kinetic resolution of the Michael donor, which was itself prepared by a domino reaction.
本文介绍了一种组装他巴氨酸及其类似物的新策略,这种类似物具有很强的生物活性。研究人员开发了一条四步通向关键中间体的路线,其中的关键步骤是高非对映选择性的迈克尔-迪克曼多米诺反应。利用不对称二羟基化反应容易获得的对映体迈克尔受体,可以对迈克尔供体进行动力学解析,而迈克尔供体本身也是通过多米诺反应制备的。
