A catalytic and highly enantioselective dearomative alkynylation of chromanones has been discovered that enables the construction of biologically relevant tertiary ether stereogenic centers. This methodology is robust, accommodating a variety of alkynes and chromanones. More than 40 substrates tested gave rise to >90% ee. Computational studies have indicated that the optimal indanyl ligand identified
已发现苯并二氢吡喃酮的催化和高度对映选择性的脱芳香炔基化,其能够构建生物学相关的叔醚立体中心。该方法非常稳健,适用于各种炔烃和色满酮。测试的 40 多种底物产生了 >90% ee。计算研究表明,在大多数情况下确定的最佳茚满基配体可能提供支持性非共价相互作用网络,从而驱动反应的对映选择性性质。
