substituent at the 2-position relative to a ring heteroatom. The convenient and straightforward method is demonstrated with reactants which are not compatible with the standard Raney nickel conditions such as sulfides, sulfones, and thiophenes. In addition, benzyl esters, benzyl amides, and benzyl carbamates are tolerated by the reductive reaction conditions.
本发明描述了一种温和的,
化学选择性的并且通常是高产率的用于还原性切割杂环
硫醚的方法。合适的杂环在相对于环杂原子的2-位具有
硫醚取代基。用与标准阮内
镍条件不兼容的反应物(例如
硫化物,砜和
噻吩)证明了这种方便,直接的方法。另外,还原反应条件容许
苄基酯,
苄基酰胺和
氨基甲酸苄酯。
