Asymmetric total synthesis of the Stemona alkaloid (-)-stenine

Stenine can be extracted from the roots of the Chinese medicinal plant Stemona tuberosa (Stemonaceae), and its structure and absolute configuration were derived by comparison to the major Stemona alkaloid tuberostemonine. We report the first enantioselect
