A base-promoted 1,5-ester shifting rearrangement reaction has been developed to access unusually functionalized seven-membered ring precursors, which could be further successfully transformed into bicyclo[3.2.1]octenes by directly closing one-carbon bridge via a key carbocation-based cyclization, providing a new and efficient route to the core of many natural products and their analogs.
已开发了一种碱促进的1,5-酯转移重排反应,以访问异常功能化的七元环前体,该碳前体可通过关键碳正离子直接关闭一个碳桥而进一步成功转化为双环[3.2.1]
