英文摘要 | Six new taxoids, taxuyunnanines W (1), X (2), Y (3), Z (5), 10-deacetyl-10-(beta-glucopyranosyl)-yunnanxane (8), and 7-(beta-xylosyl)-N-methyl-taxol C (10), as well as taxuchin B (4) and yunnanxane (7), have been isolated from the bark of Taxus yunnanensis. Compounds 1 and 2 were characterized as 11 (15-->1)-abeo taxoids containing an orthoester group, which have not been reported from any Taxus plants to date; isolates 3 and 5 are the examples of taxanes having a tetrahydronfuran ring, being reported only for the second time; and 8 is the first natural 6/8/6 skeletal type taxane glucosidic form. This is also the first report of a co-occurrence of xylosidation and N-methylation in a taxane (10). Compound 4 is the only known chlorine-containing taxane found in nature thus far, and is being reported from this plant for the first time. The structures were determined by spectroscopic and chemical means including 1D and 2D NMR spectra. (C) 2002 Elsevier Science Ltd. All rights reserved. |
