A method for producing a norbornene derivative includes forming a Mannich base represented by any of general formulae (5) to (7) by reacting a carbonyl compound represented by any of general formulae (1) to (3) and an amine compound represented by general formula (4) with each other in an acidic solvent, to thereby obtain a reaction liquid comprising the Mannich base in the acidic solvent, wherein the acidic solvent comprises a formaldehyde derivative and 0.01 mol/L or more of an acid represented by formula HX; reacting the Mannich base and a diene compound represented by general formula (8) with each other by adding an organic solvent, a base in an amount of 1.0 to 20.0 equivalents to the acid, and the diene compound to the reaction liquid, and then heating the reaction liquid, to thereby form the norbornene derivative represented by any of general formulae (9) to (11).
一种制备诺博烯衍生物的方法,包括通过在酸性溶剂中反应通式(1)到(3)中的酮类化合物和通式(4)中的胺类化合物,以形成通式(5)到(7)中的曼尼希碱基,从而在酸性溶剂中获得包含曼尼希碱基的反应液,其中酸性溶剂包括福尔马林衍生物和0.01摩尔/升或更多的通式HX的酸;通过向反应液中添加有机溶剂、1.0到20.0当量的碱和通式(8)中的二烯化合物,并加热反应液,使曼尼希碱基和二烯化合物相互反应,从而形成通式(9)到(11)中表示的诺博烯衍生物。
