| 11. | Enolate trapping with various electrophiles is decidedly less common.
|
| 12. | Pollack uses a thermodynamic argument to suggest the intermediate exists as the enolate.
|
| 13. | The next step is a redox reaction of the enolate with methylene blue.
|
| 14. | Chiral acyclic alkenes also show diastereoselectivity upon reactions such as epoxidation and enolate alkylation.
|
| 15. | Thus, enolate ions can react with electrophiles either on oxygen or on carbon.
|
| 16. | The enolate intermediate then attacks CO 2 transiently released from the enzyme linked biotin molecule.
|
| 17. | This enolate cyclizes to a cyclopropanone intermediate which is then attacked by the hydroxide nucleophile.
|
| 18. | The trisubstituted enolate is considered the triphenylmethyllithium at room temperature, giving 10 : 90 selectivity.
|
| 19. | Reacting enone with lithium metal generates the enolate at the ?-carbon of the enone.
|
| 20. | An example of a carbanionic synthon for an ester enolate is shown in fig . 1.
