The First Asymmetric Total Syntheses of (+)-Lycorine and (+)-1-Deoxylycorine
The first asymmetric total syntheses of (+)-1-deoxylycorine (2a) and (+)-lycorine (2b), the unnatural enantiomer of lycorine (1), are described. Construction of lactam 12, a key intermediate in the synthesis of both 2a and 2b, began by Birch reduction ...

In search of a cytostatic agent derived from the alkaloid lycorine: Synthesis and growth inhibitory properties of lycorine derivatives [PDF]
As a continuation of our studies aimed at the development of a new cytostatic agent derived from an Amaryllidaceae alkaloid lycorine, we synthesized 32 analogues of this natural product. This set of synthetic analogues included compounds incorporating selective derivatization of the C1 versus C2 hydroxyl groups, aromatized ring C, lactamized N6 ...

Lycorine Derivatives Against Trichomonas vaginalis [PDF]
Six lycorine derivatives were prepared, characterized, and evaluated for their in vitro anti‐Trichomonas vaginalis activity. Compounds bearing an acetyl (2), lauroyl (3), benzoyl (4 and 5), and p‐nitrobenzoyl (6 and 7) groups were synthesized. The best activity was achieved with lycorine esterified at C‐2 position with lauroyl group.

Total Synthesis of (−)-Lycorine and (−)-2-epi-Lycorine by Asymmetric Conjugate Addition Cascade
Total syntheses of (−)-lycorine and (−)-2-epi-lycorine were accomplished using chiral ligand-controlled asymmetric cascade conjugate addition methodology, which enables the formation of two C−C bonds and three stereogenic centers in one pot to give ...
