The total synthesis of umuravumbolide and hyptolide has been achieved in a efficient manner by using temporary silicon-tethered ring-closing metathesis and cross-coupling reactions as key steps. The stereogenic centres were generated by means of proline-catalysed α-aminoxylation of aldehydes and Brown's asymmetric allylation method.
通过使用暂时的硅系链闭环复分解和交叉偶联反应作为关键步骤,已经以有效的方式实现了 umuravumbolide 和 hyptolide 的全合成。立体中心是通过脯氨酸催化的醛的α-氨氧基化和布朗的不对称烯丙基化方法产生的。
