A general and highly efficient Al(OTf)3-catalyzed methodology has been developed for the direct nucleophilic substitution of the hydroxy group in propargylic alcohols with a variety of carbon- and heteroatom-centered nucleophiles such as alcohols, aromatic compounds, amides, and thiols, leading to the construction of C–C, C–O, C–N and C–S bonds.
已经开发了一种通用且高效的Al(OTf)3催化方法,用于用各种以碳原子和杂原子为中心的亲核试剂(例如醇,芳族化合物,酰胺和硫醇)直接取代炔丙醇中的羟基,导致建立C–C,C–O,C–N和C–S键。
