为了合成新结构类型查尔酮衍生物, 发现具有抗氧化活性的查尔酮类化合物, 设计合成了查尔酮A和螺杂环B两种类型, 共21个查尔酮类似物, 结构经ESI-MS, ESI-HRMS和1H NMR确认. 培养出螺杂环B1的单晶, 通过X衍射确证了其为单斜晶系. 其中螺杂环B为新结构类型化合物, 通过1,3-偶极环加成反应, 用不需加催化剂的“一锅煮”方法合成, 该反应具有很好的立体选择性和区域选择性、且环境友好. 用DPPH法测试了所有化合物的抗氧化活性, 筛选出了多个对1,1-二苯基-2-三硝基苯肼(DPPH)自由基具有良好清除率的化合物, a环3,4-OH取代的两类化合物都具有良好的抗氧化活性, 苯环邻位二羟基取代的查尔酮类化合物可能具有很好的抗氧化活性.

To synthesize new structure type chalcone analogues, and obtain chalcone analogues with good antioxidant activity. Two types of chalcone analogs, chalcones A and spiro-heterocyclic B were designed and synthesized, and the structures of 21 compounds were characterized by 1H NMR, ESI-MS and ESI-HRMS. Single-crystal of spiro-heterocyclic B was cultured, and its single-crystal structure was determined by X-ray diffraction study. The crystal structure of B1 was monoclinic system, space group C2/c, with cell dimensions of a=21.350(3) Å, b=8.6256(10) Å, c=26.161(3) Å. Spiro-heterocyclic B is the new structure type, and obtained by one-pot synthesis which is 1,3-dipolar cycloaddition reaction and no catalyst. The synthesis of spiro-heterocyclic B is not only high regioselectivity and stereoselectivity, but also environmentally friendly. The antioxidant activities in vitro were evaluated by 1,1-diphenyl-2-picrylhydrazyl (DPPH) assay. Many compounds, which can have strong activity of scavenging DPPH free radicals, were screened. In the 2 types of chalcones analogs, the compounds with 3,4-(OH)2 in “a” ring have excellent antioxidant activities. The chalcone analogs with o-dihydroxy in benzene ring maybe have good antioxidant activities.
