| Abstract: | Walsucochinoids A (1) and B (2), two rearranged limonoids possessing an unprecedented carbon framework, were isolated from Walsura cochinchinensis. Their configurations were assigned as 1S, 3R, 4R, 5R, 6R, 7S, 8R, 9R, and 10R on the basis of a detailed examination of spectroscopic data, single crystal X-ray diffraction analysis, and CD experiments. |
