We have developed a simple and practical procedure for a direct reductiveconversion from a variety of tertiaryamides to the correspondingtertiaryamines using an InBr3/Et3SiH reducing system. This reducing system can be applied to the reduction of a secondary amide and provides a more efficient alternative to conventional methods that use aluminum and boron hydrides.
我们开发了一种简单实用的程序,可使用InBr 3 / Et 3 SiH还原系统将多种叔酰胺直接还原为相应的叔胺。该还原系统可用于还原仲酰胺,并为使用氢化铝和氢化硼的常规方法提供了更有效的替代方法。
