摘要：

From the acetone extract of R. hispanica hispanonic acid (la, C2OH24O4) was isolated; CH2N2 treatment of other chromatographic fractions and extended purification yielded methyl hispanonate 1b and methyl hispaninate 6b (C21H26O4). Both products have an unusual seven-membered ring C. DDQ aromatization and catalytic hvdrogenatiori of 1b are described; fib gave a crystalline peroxide, confirming the proposed structures. Correlation of 1b and 6b was achieved through reduction products. © 1979, American Chemical Society. All rights reserved.
