, p. 14848 - 14849 (2002)
The first total synthesis of the complex pentacyclic Stemona alkaloid tuberostemonine was accomplished in 24 steps and in 1.4% overall yield from a hydroindole intermediate which is readily obtained in three steps from Cbz-L-tyrosine. An innovative synthe
Asymmetric total syntheses of tuberostemonine, didehydrotuberostemonine, and 13-epituberostemonine

Detailed experimental approaches toward the pentacyclic Stemona alkaloids tuberostemonine and didehydrotuberostemonine and the close analogue 13-epituberostemonine are described. The syntheses originate with a hydroindolinone derivative that can be obtain
Asymmetric total synthesis of the Stemona alkaloid (-)-stenine

, p. 11106 - 11112 (2007/10/03)
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
