simple secondary alcohols is reported. This one-pot cascade reaction is based on the borrowing hydrogen methodology promoted by a manganese(I) PN3 pincer complex. The reaction selectively leads to 1,2,3,4-tetrahydroquinolines thanks to a targeted choice of base. This strategy provides an atom-efficient pathway with water as the only byproduct. In addition, no further reducing agents are required.
据报道,从2-氨基苄醇和简单的仲醇开始,直接,选择性地合成1,2,3,4-四氢喹啉。此一锅式级联反应基于锰(I)PN 3钳状络合物促进的借用氢方法。由于有选择地选择了碱,该反应选择性地产生了1,2,3,4-四氢喹啉。该策略提供了以水为唯一副产物的原子有效途径。另外,不需要其他的还原剂。
