Abstract

Diels-Alder Cycloadditions of 2(1H)-Quinolones Having an Electron-Withdrawing Group at the 3-Position Acting as Dienophiles withDienes.-The title reaction is investigated under different conditions and the results are discussed on the basis of MO calculations. The structure of (VI) is determined by X-ray analysis. -(FUJITA, REIKO; WATANABE,
