| Popis: | A new diterpene, viz. 3beta-acetoxy-4alpha,18:15,16-diepoxy-6beta,12-dihydroxyneocleroda-13(16),14-dien-19,20-olide, C(22)H(28)O(8), exhibiting antifeedant activity against Spodoptera litura was isolated from the aerial parts of Teucrium tomentosum and its structure is reported. One of the two fused rings has a distorted-chair conformation and the other has a chair conformation. The molecules in the crystal are stabilized via O--H...O and C--H...O hydrogen bonds. |
