(-)-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 ...

Improvements of MFC's proton exchange membranes and cathodes
(Mohammed Premier University, 2016)
Abstract The microbial fuel cell (MFC) is well known instrument for conversion of chemical energy of organic matter into electrical. This process is driven by the specific biochemical activities of anaerobes. These organisms ...
An Efficient Synthesis of Nitriles from Aldoximes in the Presence of Trifluoromethanesulfonic Anhydride in Mild Conditions
(Maik Nauka/Interperiodica/Springer, 2020)
A new and convenient protocol has been proposed for the transformation of aldoximes to nitriles using trifluoromethanesulfonic anhydride and triethylamine. The proposed method allows a range of aldoximes, including aromatic, ...
