Indeno[1,2-c]isochromene was prepared using the readily obtainable starting materials via the condensation of dimethyl homophthalate with 3,4-dimethoxybenzaldehyde in the presence of sodium methoxide in absolute methanol followed by saponification and cyclization with concentrated sulfuric acid at 0°C. The proclivity of cyclized product for undergoing nucleophilic addition has been tested by reaction
茚并[1,2-c]异色烯是使用容易获得的原料通过在甲醇钠的存在下在无水甲醇中与3,4-二甲氧基苯甲醛缩合,然后在0°下用浓硫酸进行皂化和环化来制备的C。环化产物进行亲核加成的倾向已通过与氮亲核试剂的反应进行了测试。结构分配基于光谱数据(红外、1H NMR、13C NMR 和质谱),并由单晶 X 射线分子结构(2 和 3)证实。
