Abstract

We report a two-step sequence for the enantioselective construction of a rare family of stable C(sp)─C(sp) atropisomers featuring two additional stereogenic centers. The process begins with an organocatalyzed dihydrobenzofurannulation that establishes and controls the stereochemistry of two carbon centers, followed by a highly diastereoselective functionalization that significantly enhances the barrier to diastereomerization of the C(sp)─C(sp) bond, effectively locking and stabilizing its configuration.

摘要

我们报道了一种两步序列,用于对映选择性构建一类罕见的稳定C(sp)─C(sp)阻转异构体家族,该家族具有两个额外的立体中心。该过程始于有机催化的二氢苯并呋喃化反应,该反应建立并控制两个碳中心的立体化学,随后是高度非对映选择性官能化反应,该反应显著提高了C(sp)─C(sp)键的非对映异构化势垒,有效地锁定并稳定了其构型。
