چکیده

18.1 Enolate Ions and Enols We described in Chapters 13 and 16 that the C=O group of carbonyl compounds is reactive to attack by both nucleophiles (N:) and electrophiles (E+). We also saw in Chapter 13 that the C=O group causes Hs attached to its α-C (H-Cα-C=O) to be unusually acidic. As a result, these α-CH's are removed by bases giving enolate ions (-:Cα-C=O) Figure 18.01) that can react as nucleophiles with different electrophiles (E+) to form compounds with the general structure E-CαC=O. Figure 18.01

Carbonyl Compounds Enols and Enolate Ons. Unsaturated and Polycarbonyl Compounds

ome of the most useful reactions of carbonyl compounds involve carbonhydrogen bonds adjacent to the carbonyl group. Such reactions, which can be regarded as the backbone of much synthetic organic chemistry, usually result in the replacement of the hydrogen by some other atom or group, as in the I I I I sequence H-C-C=O -+ X-C-C=O. The important examples we I I will consider in this chapter are ...

Synthesis and carbon-carbon bond-forming reactions of tungsten, molybdenum, and rhenium enolates

Alkylation of sodium cyclopentadienyl(tricarbonyl)metal— lates of tungsten and molybdenum with o—chloro ketones and c—chloro esters gives stable tungsten and molybdenum enolates (23a—23d). Similar alkylation of sodium pentacarbonylrhenate provides rhenium enolates 24. Compounds 23 lOse carbon monoxide and rearrange to 3—oxaallyl complexes 25 upon irradia— tiøn. Compounds 25 react with benzaldeh...

A Computational Study of the Origin of Stereoinduction in NHC-Catalyzed Annulation Reactions of α,β-Unsaturated Acyl Azoliums.

The origin of stereoselectivity of NHC-catalyzed annulation reactions of ynals and stable enols was studied with Density Functional Theory. The data suggest that the C-C bond formation is the stereo-determining step. Only the deprotonated pathway (containing an oxy anion and overall neutral species) was found to give rise to discrimination of the competing stereoisomers. This is due predominant...

A cleavable linker strategy for optimising enolate alkylation reactions of a polymer-supported Evans' oxazolidin-2-one.

A cleavable linker strategy has been used to optimise the enolate alkylation reactions of a recyclable L-tyrosine derived polymer-supported oxazolidin-2-one for the asymmetric synthesis of a series of chiral alpha-alkyl acids.

Stabilization of ketone and aldehyde enols by formation of hydrogen bonds to phosphazene enolates and their aldol products.

Solution properties of enolates generated using the phosphazene (Schwesinger) base P4-tBu were investigated by NMR spectroscopy. With a full equivalent of base the benzyl ketones 1a and 1b, the acetophenone 2, the arylacetaldehyde 1c, and the methyl arylacetate 1d formed the expected "naked" (P4H+) enolates 3 and 7. However, at a half-equivalent of base the ketones 1a and 1b as well as the alde...
