| 11. | Third, the products of the Sharpless epoxidation frequently have enantiomeric excesses above 90 %.
|
| 12. | Scopine can be prepared by the hydrolysis of Prilezhaev epoxidation with trifluoroperacetic acid affords scopine.
|
| 13. | In the first pathway, ( + )-costunolide undergoes enzymatic epoxidation forming parthenolide.
|
| 14. | This indicates that MupO is either not involved or is not essential for this epoxidation step.
|
| 15. | Stilbene undergoes reactions typical of alkenes, being susceptible to bromination, epoxidation, and cycloaddition.
|
| 16. | It can be prepared by epoxidation of styrene with peroxybenzoic acid, in the Prilezhaev reaction:
|
| 17. | Phase-transfer catalysis of nucleophilic epoxidation is also possible using cinchona-based alkaloid catalysts.
|
| 18. | Antheraxanthin is a partially de-epoxidized ( see de-epoxidation ) form of violaxanthin.
|
| 19. | After 1, 4-elimination, the diene undergoes an epoxidation ( Step D ).
|
| 20. | Furthermore, the enantioselective epoxidation of conjugated dienes is much higher than that of the nonconjugated dienes.
