A novel palladium-catalyzed ring-opening reaction of oxabicyclic alkenes with arylsulfonyl hydrazides was first developed. In this work, we provide an efficient one-pot reaction to afford the corresponding cis-2-aryl-1,2-dihydronaphthalen-1-ols and 2-aryl-naphthalenes in moderate to excellent yields (up to 95%) under an open-air condition. Various types of functional groups attached to the substrates
首先开发了新型的钯催化的氧杂双环烯烃与芳基磺酰肼的开环反应。在这项工作中,我们提供了一种有效的一锅法反应,在中等温度下(以高达95%的产率)提供相应的cis-2-芳基-1,2-二氢萘-1-醇和2-芳基萘(高达95%)。露天条件。用这种方法可以很好地耐受附着在基质上的各种类型的官能团。其中,通过X射线晶体学分析证实了产物3ag的顺式-1,2-构型。此外,还提出了一种可行的开环机构。
