Reactivity of 5-Methyl-3(2H)-furanones toward Schiff Bases; Synthesis of 5-Styryl-3(2H)-furanone Derivatives

10.1055/s-1981-29328

The research investigates the reactivity of 5-methyl-3(2H)-furanones towards Schiff bases, aiming to synthesize 5-styryl-3(2H)-furanone derivatives. The study demonstrates that the reaction of Schiff bases with ketones, which is formally analogous to the aldol reaction, is feasible under acidic conditions. Key chemicals used include 4-ethoxycarbonyl-5-methyl-3-oxo-2,3-dihydrofuran (1), various imines (2), and acetic acid. The researchers found that the reaction proceeds stereospecifically to form (Z)-2-benzylidene-4-ethoxycarbonyl-3-oxo-5-(E)-styryl-2,3-dihydrofurans (3) when two mol equivalents of imines are used. For compounds with different aryl groups, an intermediate (4) is first prepared and then reacted with a second Schiff base. The study concludes that the 5-methyl-3(2H)-furanone system exhibits high reactivity, and the synthesized compounds' structures are confirmed by microanalyses and spectral data.
