In order to expand the utility of the reaction, modification of the route to anilidomethylene malonic ester equivalents was developed. Simple condensation of triethyl orthoformate with cyanoacetic ester, acetoacetic ester, or malonic ester in the... [Pg.425]

As enolate precursors can be used CH-acidic carbonyl compounds such as malonic esters, cyanoacetic esters, acetoacetic esters and other /3-ketoesters, as well as aldehydes and ketones. Even CH-acidic hydrocarbons such as indene and fluorene can be converted into suitable carbon nucleophiles. [Pg.201]

When a new carbon-carbon bond is produced by nucleophilic addition to conjugated systems, the process is called Michael addition. The generalised process involves an a, b-unsaturated compound and a compound containing an active hydrogen attached to a carbon atom (e.g., malonic ester, acetoacetic ester, nitrocompounds, aldehydes, ketones etc.) These are condensed in the presence of a base. The overall reaction and its mechanism can be represented as follows ... [Pg.220]

Reaction XLIV. (b) Condensation of Alkyl and Aryl Halogen Compounds with the Sodio- and other Metallo-derivatives of Ethyl Aceto-acetate and its Homolognes. (A., 186, 214 201, 143 213, 143.)—Like malonic ester, acetoacetic ester contains two 1 3-carbonyl groups with a methylene group in position 2. It is only to be expected then that it yields with metallic sodium or sodium alcoholate sodio-derivatives from which mono- and di-, alkyl and aryl homologues can be obtained by treatment with a suitable halide, including halogen esters. Acetoacetic acid... [Pg.137]

Because of the acidity of their methylene hydrogens malonic esters, acetoacetic esters, and similar compounds are often called active hydrogen compounds or active methylene compounds. Generally speaking, active hydrogen compounds have two electron-withdrawing groups attached to the same carbon atom ... [Pg.844]

Frankland had a beneficial influence on the teaching of chemistry in England. He wrote some good text-books, one in collaboration with Japp. Frankland s papers were collected and edited by himself but unfortunately the text of the originals is sometimes modified. His researches on organo-metallic compounds, the synthesis of esters from acetic ester, acetoacetic ester, and flame and combustion, and his theory of valency will be dealt with in the... [Pg.501]
