• 論文の詳細を見る

• A reinvestigation of Cantrell's thermal cycloaddition of tropone to 1,1-diethoxyethene has led to the isolation of three products: [4+2], [6+2], and [8+2] cycloadducts. The structure of the [4+2] cycloadduct was revised on the basis of an NMR analysis of the hydrolyzed diketone, and newly identified was a superficial <I>anti</I>-Woodward–Hoffmann [6+2] cycloadduct. These adducts did not cause mutual isomerization by heating under formation conditions.
