Enols reactions with

S. o-Hydroxydibenzoylmethane can be crystallized from 95% ethanol and forms crystals melting at 120°, which give a strong enol reaction with ferric chloride. Crystallization is not necessary here. [Pg.75]

Tellurium O-ethyldipropionylmethane trichloride (Formula III), isolated as indicated above, crystallises from a mixture of chloroform and petroleum (B.pt. 40° to 60° C.) as transparent lemon-yellow prisms, M.pt. 110° to 111° C. with blackening and decomposition. It yields pale yellow solutions in cold organic solvents, and gives no enolic reaction with feme chloride in aquo-alcoholic chloroform solution, but decomposes rapidly, giving a yellow turbidity. With aqueous alkalis it develops the earthy odour of the free O-ether of dipropionylmethane. [Pg.254]

Dimethylpyrone tellurioxychloride is obtained as noted above. About 0 3 gram of colourless crystals, M.pt. 115° C., is isolated. The product is soluble in chloroform, insoluble in benzene and light petroleum. It gives no enolic reaction with ferric chloride, no odour with aqueous alkali, and is hydrolysed by water, but not so rapidly as the tellurichloride. [Pg.258]

A multinuclear Zn-binaphthoxide complex prepared from Et2Zn and the linked-BINOL 28 has recently been developed as an effective catalyst for the Michael reaction (Scheme 13) [15], The a-hydroxy acetophenone derivative 29 was a suitable substrate, reacting with the Zn complex to afford the configurationally stable Zn enolate. Reaction with a variety of enones proceeded smoothly and... [Pg.354]

Chapter 24 concentrates on the second general reaction of enolates—reaction with other carbonyl compounds. In these reactions, one carbonyl component serves as the nucleophile and one serves as the electrophile, and a new carbon-carbon bond is formed. [Pg.917]

B. Enolate Reactions With Acid Derivatives The Thorpe-Ziegler disconnection is... [Pg.753]

With unsymmetrical ketones, a mixture of regioisomeric enolates may be formed, resulting in a mixture of Michael adducts. Deprotonation in a protic solvent is reversible and leads predominantly to the thermodynamically favoured, more-substituted enolate. Reaction with a Michael acceptor then gives the product from reaction at the more-substituted side of the ketone carbonyl group. The 1,5-dicarbonyl compound 24 is the major product from conjugate addition of 2-methylcyclohexanone to methyl acrylate using potassium tert-butoxide in the protic solvent tert-butanol (1.39). In contrast, the major product from Michael addition... [Pg.21]

Furthermore, the product of the enolate reaction with the electrophile can be converted into a new, more substituted enolate that can be introduced into a reaction with another electrophile (Figure 10.2) Overall, this symphony of stereoelectronic effects opens synthetic access to both (R) and (S) isomers of a variety of P-amino acids from a common chiral starting material. [Pg.258]
