The first enantioselective vinylogous Mukaiyama-type dearomatisation of heteroarenes under anion-binding catalysis is presented. A recyclable tetrakistriazole catalyst was used for the enantiocontrol of the remote vinylogous active position of silyl dienol ethers. This approach provided chiral heterocycles bearing α,β-unsaturated chains with complete regioselectivity and excellent enantioselectivities
提出了阴离子结合催化下杂
芳烃的第一个对映选择性插烯 Mukaiyama 型脱芳构化反应。使用可回收的四三唑催化剂来对甲
硅烷基二烯醇醚的远程插烯活性位置进行对映控制。这种方法提供了带有 α,β-不饱和链的手性杂环,具有完全的区域选择性和优异的对映选择性(高达 97.5 : 2.5 er)。
