Synthesis of 1,2,3-Butatrienecarboxylic Acids
The first butatrienecarboxylic acids, the triphenyl derivative 1 and the two E/Z isomeric dicarboxylic acids 2 and 3, have been prepared. Whereas 2, R1 = tBu, is configurationally stable in solution at room temperature, 3, R1 = Ph, isomerizes under these conditions; the E form predominates in the eq...

| Zusammenfassung: | The first butatrienecarboxylic acids, the triphenyl derivative 1 and the two E/Z isomeric dicarboxylic acids 2 and 3, have been prepared. Whereas 2, R1 = tBu, is configurationally stable in solution at room temperature, 3, R1 = Ph, isomerizes under these conditions; the E form predominates in the equilibrium (R = H). |
