Abstract

PURPOSE: To prepare the titled compound useful as a precursor of cis-jasmine, etc., in high yield, by isomerizing dihydrofuran with a VIII-group transition metal hydride complex, reacting the product with an alcohol, and hydrolyzing the resultant tetrahydrofuran compound.
CONSTITUTION: A dihydrofuran compound of formulaI(R is alkyl or aryl; X is H, alkoxycarbonyl, alkyl or aryl) is used as the starting material, and is isomerized with a VIII-group transition metal hydride complex[e.g. dihydrido(carbonyl)tris(triphenylphosphine)-ruthenium]to obtain the dihydrofuran compound of formula II, which is converted to the tetrahydrofuran compound of formula III with an alcohol (e.g. methanol, ethanol, etc.) and then hydrolyzed to obtain the γ-ketocarboxylic acid of formula IV and its ester.
