本論文主要在討論有關於拉電子基取代之6-(4-methoxyphenyl) fulvene和給電子基不對稱“單”取代在8,8-dicyanoheptafulvene為催化劑下加熱進行 [m+n] 環化加成反應之研究;對其進行環化加成反應之相互之間的反應性、立體選擇性（ Diastereoselectivity ） 、位置選擇性（ Periselectivity ）和位向選擇性（Regioselectivity），有進一步徹底而詳細的研究探討。
實驗結果顯示，在室溫的溫和反應條件下，8,8-dicyanoheptafulvene和給電子基不對稱單取代之 6-(4-methoxyphenyl) fulvene 反應，則會顯示出百分之百之endo 立體選擇性和反向（anti）位向選擇性與不錯之位置選擇性，進行〔6+4〕環化加成反應得到反向（anti）-endo-〔6+4〕環化加成生成物 23n / 23n’（1:1）。
The investigation of this research involves the synthesis and intermolecular [m+n] cycloadditions of the unsymmetrically electron-rich 6-monosubstituted 6-(4-methoxyphenyl)fulvene with 8,8-dicyaoheptafulvene ; designed to establish the experimental analyses of the reactivity, diastereoselectivity, periselectivity, and regioselectivity of these cycloadditions.
The cycloaddition reaction of 8,8-dicyanoheptafulvene with 6-(4-methoxyphenyl)fulvene at room temperature gave the anti-endo-[6+4] cycloadducts 23n/23n’(1:1 ratio) and. The present results show that these [6+4] cycloaddition reactions took place with exclusive endo diastereoselectivity and anti regioselectivity. Good periselectivity was also observed.
