2,3-二氢-4H-砒喃并[2.3-f]异喹啉-4-酮衍生物的合成研究

The synthesis of derivatives of 2,3-dihydro -4H-pyrano[2 3-f]isoquinolin-noe

由２ ，３ － 二氢－ ４ Ｈ－ 砒喃并［２ ，３ － ｆ］ 异喹啉－ ４ － 酮与取代糠醛为原料，通过碱性催化的羟醛缩合反应合成了标题化合物，通过元素分析， Ｉ Ｒ 和 Ｎ Ｍ Ｒ 光谱确定了全部新化合物的结构，并讨论了反应机理．

The title compounds were synthesized by the aldol condensation reaction of 2,3-dihydropyrano[2 3-f]isoquinolin-4-one and substituted furaldehyde under the alkaline condition.Their structures were confirmed by elemental analysis,IR and 1H NMR spectra.The reaction mechanism was discussed.
