β,β,γ,γ-Tetracyanoalkanones react with acrolein at a high rate to afford the corresponding 2-substituted 4-formyl-3-cyclopentene-1,1,2-tricarbonitriles in high yields. The reaction occurs under mild conditions and is quite applicable for modification of natural and biologically active compounds possessing an R′CHC(O)CR3 fragment to obtain their derivatives containing three cyano groups.
β,β,γ,γ-四氰基烷酮与丙烯醛在较高反应速率下反应,以高产率生成相应的2-取代-4-醛基-3-环戊烯-1,1,2-三氰基化合物。该反应在温和条件下进行,非常适用于具有R'CHC(O)CR3片段的天然和生物活性化合物的修饰,以获得含有三个氰基的衍生物。
