An attempted oxidative coupling approach to the scholarinine A framework. | LitMetric

AI Article Synopsis

  • - The manuscript investigates a reaction that builds carbon-carbon bonds, specifically focusing on creating alkaloid structures like scholarinine A using a constrained substrate.
  • - Instead of achieving the expected carbon-carbon bond between indole and malonate, a carbon-nitrogen bond was formed, indicating competitive reactivity.
  • - This study highlights the complexities involved in oxidative carbon-carbon bond formation, particularly when dealing with conformationally constrained substrates.

Article Abstract

In this manuscript, an oxidative carbon-carbon bond forming reaction to construct the framework of alkaloids such as scholarinine A is explored using a constrained substrate. Instead of the desired carbon-carbon bond formation between an indole C3 position and a malonate group, a competing carbon-nitrogen bond between the malonate and indole C3 position was observed to form. This work adds to the growing body of substrates for oxidative carbon-carbon bond formation and importantly, demonstrates that these reactions are challenging for some conformationally constrained substrates.
