As the replacement of a hydrogen atom by a fluorine atom in a compound can have an important impact on its biological properties, the development of methods allowing the introduction of a fluorine atom is of great importance. The scope and limitations of the ring expansion of cyclic 2-hydroxymethyl amines induced by diethylaminosulfur trifluoride (DAST) to produce cyclic β-fluoro amines was studied
由于化合物中的氟原子取代氢原子对其生物学特性有重要影响,因此开发允许引入氟原子的方法非常重要。研究了二乙基氨基三氟化硫(DAST)诱导生成环状β-氟胺的环状2-羟甲基胺环扩环的范围和局限性,以及该方法的对映选择性。
