制备方法与用途

背景 烯烃复分解反应是有机化学中最为重要和实用的一类反应，它使通常难以反应的双键能够彼此偶联，极大地拓展了构造化合物骨架的可能性。由于这种反应条件温和、产率高，并且绝大多数有机基团在这一过程中无需保护，近年来受到了学术界和工业界的广泛重视。金属卡宾化合物因其能有效催化各种类型的烯烃复分解反应而备受关注，尤其是Grubbs催化剂。

简介 Grubbs催化剂是一种用于烯烃复分解反应的配位化合物，其配体对催化剂的性能和稳定性有很大影响。

特性 Grubbs二代催化剂通过将第一代催化剂中的三环己基膦配体替换为二取代二氢咪唑配体而制得。这种配体中氮原子取代基的空间位阻效应和电子效应使得Grubbs二代催化剂在反应过程中更为稳定，不易发生分解。与第一代催化剂相比，它不仅具有更强的稳定性，还表现出更高的反应活性。

设计理念 Grubbs二代催化剂的设计理念是用比磷配体具有更强给电子能力和更高稳定性的N-杂环卡宾配体取代其中一个磷配体。

用途 相比于第一代催化剂，Grubbs第二代催化剂更具活性且能广泛应用于不同类型的底物，包括对空间有要求或容易失活的烯烃，如1,1 - 二取代烯烃和α，β-不饱和羰基化合物。

  摘要：

  瓜瓜毒素3C ABCDEF环的合成是通过以下途径实现的，该方法包括将对应于AB环的二甲基二硫缩醛单-S-氧化物衍生物和对应于EF环的醛进行阴离子偶联，然后使用还原醚化进行环化。AB-环是从已知的基于闭环烯烃复分解的d-葡萄糖衍生物合成的，而EF-环是通过采用手性转移爱尔兰-克莱森重排和闭环烯烃复分解的方法制备的。
