Die STOBBE-Kondensation mit Homophthalsäure-dimethylester. Teil 1Die Kondensation von Methyl-α-thienylketon, Methyl-α-furylketon und Phenyl-2-thienylketon mit Homophthalsäure-dimethylester in Gegenwart von Kalium-tert.-butanolat oder Natriumhydrid als Kondensationsmittel ergab hauptsächlich die (z)-Halbester. Die Struktur und Konfiguration der Produkte wurde chemisch und spektroskopisch ermittelt.
Notes:
The condensation of methyl 2-thienyl, methyl 2-furyl, and phenyl 2-thienyl ketone with dimethyl homophthalate in the presence of either potassium t-butoxide or sodium hydride as condensing agent, gave predominantly the (z)-half estersThe nomenclature of cis/trans isomers follows the IUPAC Tentative rules, Section E, Fundamental Stereochemistry, J. org. Chemistry 35, 2849 (1970). See also N. R. El-Rayyes, J. prakt. Chem. 315 (2), 300 (1973). (E) = trans-(Heterocyclic ring/CO2CH3) (Z) = cis-(Heterocyclic ring/CO2CH3). The structure and configuration of the products were inferred by chemical and spectroscopic means.
