| 摘要 | Two new monoterpenoid indole alkaloids, vincamajorines A (1) and B (2), were isolated from Vinca major. Their structures were elucidated by means of 1D and 2D NMR, and HREIMS spectroscopic data. The relative and absolute configurations were deduced by comparing the experimental C-13 NMR, ECD spectra, and OR data with those theoretically calculated. Vincamajorine A (1) represents a new C-20 carbon skeleton arranged compactly in seven rings, and vincamajorine B(2) is an alkaloid with an unprecedented 6/5/7/5/6 pentacyclic ring system. A possible biosynthetic pathway was also proposed for the formation of 1 and 2. (C) 2014 Elsevier Ltd. All rights reserved. |
