The most widely studiedof imidazoliumcyclophanebecause of the positive charge on the imidazolium,which makes the C-H activity on the imidazole ring can generate hydrogen bonds with the guest molecule or be removed in an alkaline environment to form carbene.Based on the good recognition performance of imidazole ring compound and the 3D structure of carborane.The introduction of carborane into the imidazolium ring can increase the stereo configuration and cavity size,which will be better for the detection of organic pollutants 1-2.Basd on this idea,1,2-diaryl-o-borane was used as the basic framework,and hydroquinone ethoxylate and pyridyl group was used as bridging group to [1+1] quaternized high-efficiency oriented ring closure.Fluorescence experiment shows that the receptor Acan selectively recognize p-aminophenol neutral molecules by forming intermolecular hydrogen bonding and π-π stacking.

有机分子的精准官能团化是有机合成研究的重要方向，导向基诱导过渡金属催化的选择性碳氢键官能团化是强有力的工具之一.但其局限性在于需要额外的步骤来对底物进行预活化或者脱除导向基，从而降低了合成的效率.最新的策略是利用瞬态导向基可逆地和底物结合，实现位点选择性的惰性碳氢键官能化1.最近，我们通过加入催化量的氨基酸或苯胺衍生物与芳香醛或苯甲酰甲酸酯动态可逆形成亚胺，此亚胺通过双、单齿引导过渡金属钯、铱、钌
燕麦生物碱是由加拿大科学家Collins首次分离鉴定,并且命名为Avenanthramides,其中主要的三种是由Collins定义的燕麦生物碱A、B、和C.燕麦生物碱不仅有很强的抗氧化作用,而且具有止痒、抗增殖、抗炎等多种生物活性,对冠心病、结肠癌和皮肤瘙痒症的防治也起到了重要的作用,引起国内外学者的极大兴趣[1].近年来,国内外主要以皮燕麦为主要原料研究燕麦生物碱的含量、提取工艺及其生物活性等
对C-葡萄糖苷SGLT2抑制剂类化合物近端苯环的C6部位用不同官能团进行取代，在远端苯环上连接氮原子和体积较大的取代基，考察空间位阻对活性的影响.同时对合成过程中的反应时间、反应温度、反应溶剂、投料比等变量进行单因素筛选和优化，中间体2、4d和5d的产率分别达到了73.48％、72.38％和78.25％，目标化合物9c的产率达到了70.O9％.设计并合成了4个未见文献报道的新化合物，并通过核磁共振
