ABSTRACT In close quarters: A concise, high-yielding, and more sustainable route for the synthesis of (±)-mersicarpine in nine linear steps from commercially available indole and succinic anhydride is presented. It is also demonstrated that the novel protocol can be commonly used for the rapid and flexible construction of a diverse class of mersicarpine analogues.
