基本信息
| 应用 | Potassium osmium(VI) oxide dihydrate acts as a catalyst for the oxidative cleavage of olefins to ketones and carboxylic acids. It is employed in an intramolecular amidohydroxylation of carbamoyloxytethered olefins providing hydroxy oxazolidinones. It is also used as a reagent in the synthesis of amphidinolide B, which shows potent antitumor activity against human solid and blood tumor cells. |
