本論文係主要利用具有強烈拉電子官能基的活潑烯類分子I分別進行有機合成。首先當R1為苯甲醯基時,烯類分子I在醯氯化合物與三丁基膦反應下可形成Wittig試劑,接著在三乙基胺反應下,可生成多官能基取代的呋喃化合物II;當R為乙酯基以及R1為氫原子時,在三丁基膦反應下亦可形成另一種Wittig試劑,接著與醛類化合物進行反應,可生成多官能基取代烯類分子III;而當R與R1同為氫原子時,分別在二苯基乙基膦催化下,與醛類分子以及親核性試劑反應,或在三苯基膦催化下,與亞胺分子以及親核性試劑反應,可生成多官能基取代的三組分產物IV;最後在二級胺催化劑催化下與環己酮進行有機不對稱加成反應,可生成多官能基取代的不對稱產物V。
