【摘要】

：

PPA即多聚磷酸(Polyphosphoricacid),其具有强脱水性、低亲核性、适度酸性,其很少将反应物氧化,能溶于有机溶剂.在有机合成研究中,大量研究表明,PPA在环化、缩合、水解、重排等方面均具有显著的催化作用[1].在二十世纪,研究者就用其作催化剂,最为常用的是作为一种关环试剂在有机合成反应中.其在分子内闭环缩合方面,有着其特殊的优点[2].PPA在有机合成中的应用,是反应简单化的同时,

非金属催化酚羟基醛与二酮化合物反应合成含氧桥环衍生物

桥环骨架化合物种类繁多,如：碳桥环化合物(a)、氮桥环化合物(b)、氧桥环化合物(c)等,这些桥环骨架化合物在天然产物及药物中广泛存在。在有机合成中,桥环化合物不仅是重要的反应中间体和活性中心,同时也可以通过进一步的衍生反应来构建手性中心。然而,由于桥环化合物环张力较大,不稳定,通常难以合成。一直以来,桥环及其衍生物的合成都是有机合成化学领域颇具挑战性的课题。本文通过酚羟基醛和2,4-二酮衍生物在
