Ester enolization

Ester Enolates- Esters are susceptible to substitution by the base, even LDA can be problematic. Use very hindered non-nucleophillic base (Li isopropylcyclohexyl amide)... [Pg.73]

Lewis acid promoted condensation of silyl ketene acetals (ester enolate equiv.) with aldehydes proceeds via "open" transition state to give anti aldols starting from either E- or Z- enolates. [Pg.86]

Step 2 Nucleophilic addition of the ester enolate to the carbonyl group of the neutral ester The product is the anionic form of the tetrahedral intermediate... [Pg.888]

Most of the reactions of ester enolates described so far have centered on stabilized eno lates derived from 1 3 dicarbonyl compounds such as diethyl malonate and ethyl ace toacetate Although the synthetic value of these and related stabilized enolates is clear chemists have long been interested m extending the usefulness of nonstabilized enolates derived from simple esters Consider the deprotonation of an ester as represented by the acid—base reaction... [Pg.902]

Ester enolates generated by proton abstraction with dialkylamide bases add to aldehydes and ketones to give (3 hydroxy esters... [Pg.903]

The critical carbon-carbon bond forming step requires nucleophilic substitution on an alkyl halide by an ester enolate Methyl halides are more reactive than... [Pg.904]

Section 21 10 It is possible to generate ester enolates by deprotonation provided that the base used is very strong Lithium diisopropylamide (LDA) is often used for this purpose It also converts ketones quantitatively to their enolates... [Pg.907]
