  摘要：

  通过开发 ProPhenol/Ti(IV) 催化剂，使用 TBHP 作为简单的氧化剂实现了萘酚的催化对映选择性羟基化脱芳构化。β-萘酚C1位的侧配位链对引发这种不对称羟基化反应起着重要作用，这可能是催化剂中钛中心适当配位作用的结果。提出了合理的催化循环，将催化体系应用于该类酚类化合物的合理范围，并进行了相关的简明改造。

With KOAc as the base, subsequent oxidative C(sp3)–H/C(sp3)–H coupling occurs; in this case, the overall transformation achieves triple C–H activation to form three new C–C bonds. These reactions allow expedient access to 2,6-dimethylated phenols, 2,3-dihydrobenzofurans, and indanes, which are ubiquitous
