| 摘要 |
The stereoselective expoxidation of cyclic 4-hydroxy olefins is disclosed. These methods involve contacting the cyclic 4-hydroxy olefin with peroxycarboximidic acid, which is preferably generated in situ by contacting an organic nitrile with aqueous hydrogen peroxide. The invention provides unexpectedly high yields of the corresponding cis-epoxides.
