(-)-Tubifolidine as strychnos indole alkaloid: Spectroscopic charactarization (FT-IR, NMR, UV-Vis), antioxidant activity, molecular docking, and DFT studies
(Elsevier, 2021)
Strychnos indole alkaloids, which include tubifolidine (2) and are an important group of complex and interesting natural compounds as bio-actives, antioxidants as well as ABCDE ring system. Four different procedures have ...
An Effective Approach to the Strychnos Alkaloids: Total Synthesis of Tubifolidine
(Springer, 2021)
A facile total synthesis of tubifolidine has been developed, which is accomplished in an 11-step synthesis of the ABCDE pentacyclic of the strychnos alkaloids with an overall yield of 10%. The key steps are the cyclization ...
