Since being introduced by Schmalz et al,1 alkynylcyclopropane(ACP)ketone has recently been proved to be a versatile building block in organic synthesis.As a novel type of donor-acceptor cyclopropane,ACP ketone has also got attractive attentions in recent years for its novel types of cycloaddition.2,3 In these cycloadditions,ACP ketones were mostly used as 1,4-dipoles2 and the examples of ACP ketones as 1,3-dipoles3 were quite limited.Herein,we report a Lewis acid-catalyzed intermolecular [3+2] cycloaddition of ACP ketones with electron-rich aromatic aldehydes,by which 2,5-trans-tetrahydrofurans were constructed diastereoselectively.

冠醚与碱金属、碱土金属有良好的配位作用，在过去的数十年中基于大环冠醚络合分离碱金属、碱土金属离子(特别是锂离子)的技术被广泛研究。如冠醚液液萃取法、基于冠醚主体的离子交换树脂法等。然而，传统的冠醚尽管对金属离子的络合能力较强，但存在反萃率低、电荷不呈中性等缺陷。因此，对于相应的分离技术仍然存在挑战。在此，我们引入了硼原子辅助冠醚关环，由于硼氧关环可被亲硼性氟离子开环而发挥选择性的离子络合开关作用，
本研究以抗肿瘤药喜树碱为模板,DT1 为功能单体、DT2 为第一交联剂、马来松香丙烯酸乙二醇酯为第二交联剂,利用马来松香丙烯酸乙二醇酯交联剂较好的手性空间立体选择性和机械强度,通过悬浮聚合法合成松香基手性高分子印迹聚合物,其粒径主要集中在50um.将松香基手性高分子印迹聚合物作为固定相,获得松香基手性高分子印迹色谱柱,用高效液相色谱法评价其识别位点和喜树碱之间的匹配程度,研究其印迹效果和分离性能.
