The metal-free reduction of nitroarenes to aniline derivatives was accomplished in a short time by using a benzothiazoline as the hydrogen donor in combination with a Bronsted acid. An enantioselective synthesis of 2-arylquinolines was achieved by using 1-aryl-3-(2-nitrophenyl)propan-1-ones as starting materials and a combination of a benzothiazoline and a chiral phosphoric acid.
通过使用苯并噻唑啉作为氢供体并结合布朗斯台德酸,在短时间内完成硝基芳烃向苯胺衍生物的无金属还原。2-芳基喹啉的对映选择性合成是通过使用 1-芳基-3-(2-硝基苯基)丙-1-酮作为起始材料以及苯并噻唑啉和手性磷酸的组合来实现的。
