摘　　要：环糊精(CDs)是由6,7或8吡喃葡萄糖与上下环绕的羟基组成的环状低聚糖,具有内疏水外亲水的结构特征。合成了一种酰化的γ-环糊精(CDs),并将酰化的环糊精衍生物与trans-2-苯乙烯吡啶分子包合,比较了固态、液态及凝胶态中包合物的光反应结果,发现修饰的环糊精对其分子内光环化产物的生成具有选择性,其中固态产物的选择性最好,可以得到产率较高的苯并[f]喹啉。Cyclodextrins （CDs） are doughnut shaped cyclic oligosaccharides consisting of six, seven or eight glucose units with a hydrophobic inner cavity and a hydrophilic exterior. Acylated γ-cyclodextrins （CDs） was synthesized, then could include trans-2-styrene pyridines to form inclusion complexes. The inclusion complexes were used to conduct the photoreaction in solid, liquid, gel state through the comparison. It was found that the modified cyclodextrins could induce selectivity in unimolecular cyclization, the solid product selectivity was best; the higher yield of benzo [f] quinoline could be got.
