Abstract
Four new oxindole alkaloids, paratunamides A-D (1-4), containing a secologanin unit, were isolated from the bark of Cinnamodendron axillare, and their structures and relative configurations were elucidated by spectroscopic data. The absolute configuration at C-7 in 1-4 was assigned as S, S, R, and S, respectively, on the basis of the CD spectra.
摘要
从腋花樟的树皮中分离出四种新的含有裂环马钱子苷单元的氧化吲哚生物碱，即副番荔枝酰胺A-D（1-4），并通过光谱数据阐明了它们的结构和相对构型。根据圆二色光谱，1-4中C-7位的绝对构型分别指定为S、S、R和S。
