Stachyodin A, possessing a unique spirotetrahydrofuran ring system, was isolated from the roots of Indigofera stachyodes in 2018. The first total synthesis of racemic stachyodin A was accomplished in 14 steps. The efficient stereoselective synthetic route involved one-pot Suzuki coupling and stereocontrolled epoxidation followed by reductiveopening and spirocyclization.
