route for the deoxygenative reduction of primary to tertiary amides to corresponding amines has been achieved with pinacolborane (HBpin) using simple and readily accessible 2,6-di-tert-butyl phenolate lithium·THF (1a) as a catalyst. Both experimental and DFT studies provide mechanistic insight.

amides to amines is a great challenge for resonance-stabilized carboxamide moieties, although this synthetic strategy is an attractive approach to access the corresponding amines. La(CH2C6H4NMe2-o)3, a simple and easily accessible lanthanide complex, was found to be highly efficient not only for secondary and tertiary amide reduction, but also for the most challenging primary reduction with pinacolborane
酰胺脱氧还原为胺对于共振稳定的羧酰胺部分是一个巨大的挑战,尽管这种合成策略是获得相应胺的有吸引力的方法。La(CH 2 C 6 H 4 NMe 2 - o ) 3是一种简单易得的镧系元素络合物,被发现不仅对于仲酰胺和叔酰胺还原非常有效,而且对于频哪硼烷最具挑战性的初级还原也是如此。该方案对许多官能团和杂原子表现出良好的耐受性,可应用于克级合成。该催化循环中的活性物质可能是镧系元素氢化物。
