journal contribution
posted on 2017-10-12, 12:02 authored by Wei Li, Gui-Hua Tang, Lin Chen, Ya-Qi Tang, You-Kai Xu, Bo Liu, Sheng YinPhytochemical investigation of Strychnos nitida has led to the isolation of three new racemic pyridocarbazole alkaloids, (±)-stritidas A-C (1–3) and three known monoterpenoid indole alkaloids (4–6). Compounds 2 and 3 represent the first examples of pyridocarbazole alkaloids featuring an N-2-hydroxyethyl moiety. Their structures were determined by combined spectroscopic data (MS, UV, IR and NMR) and chemical methods.
