The reactions of β-cyanoacrolein or its dimethyl acetal were investigated. Various new compounds were prepared by the application of several basic reactions, namely, oxidation, reduction, addition, and others. Moreover, β-cyanoacrolein was found to react as a dienophile or as a diene in Diels-Alder reactions. In the reaction with butadiene, isoprene, and 1, 3-pentadiene, cyanotetrahydrobenzaldehyde
研究了β-氰基丙烯醛或其二甲基乙缩醛的反应。通过应用几种基本反应,即氧化、还原、加成等,制备了各种新化合物。此外,发现 β-氰基丙烯醛在 Diels-Alder 反应中作为亲二烯体或作为二烯反应。在与丁二烯、异戊二烯和1,3-戊二烯的反应中,得到氰基四氢苯甲醛衍生物。当使用乙基乙烯基醚或丁基乙烯基醚作为亲二烯体时,制备出二氢吡喃衍生物;该吡喃用稀盐酸水解成2-氰基戊二醛。
