A new approach to the macrocyclic lactone zearalanone is described utilizing an alkenol and an arene trifluoromethanesulfonate as starting materials. The key step is a Pd(0)-catalyzed cross-coupling of the arene trifluoromethanesulfonate with a 9-alkyl-9-borabicyclo[3.3.1]nonane derived from the alkenol. The title compound is obtained by macrolactonization of a hydroxy acid under Mitsunobu conditions
描述了一种新的大环内酯齐拉丙酮的制备方法,该方法以烯醇和芳烃三氟甲磺酸盐为原料。关键步骤是芳烃三氟甲磺酸酯与衍生自烯醇的9-烷基-9-硼环[3.3.1]壬烷的Pd(0)催化交叉偶联。通过在 Mitsunobu 条件下羟基酸的大环内酯化获得标题化合物 。
