本研究之目的在使用常見的自由基誘發劑-過氧化苯甲醯基
（benzoyl peroxide），以自由基取代反應（加成-離去）的策略，
將雜環或環烷類官能團有立體選擇性的引入，來合成苯乙烯類衍生
物。使用這個方法，可以在廣泛的受質應用上都有高反應性與高選擇
性。這個使用易取得、且具有一鍋到底反應潛力之起始物的反應，在
所有的例子中，都有著優秀的反式-選擇性並伴隨著中到高等的產
率。在此，將利用製備各式各樣的反式-苯乙烯類衍生物，來說明此
方法的合成價值。

Abstract
Stereoselective styryl derivatives have been prepared based on
radical substitution (addition-elimination) of heterocycles or
cyclohydrocarbons units to (E)- β-nitrostyrenes 1 using a common radical
initiator-benzoyl peroxide. High reactivity and selectivity with wide
substrate scope were attained by using this easy methodology. The
reactions using easily obtained and one-pot potential starting materials
gave excellent trans-selectivity with medium to high yields in all cases.
Synthetic utility of this approach has been demonstrated by the
preparation of various trans-styryl derivatives.
