The development of a Selectfluor®-mediated oxidative Mannich reaction
摘要:
Selectfluor (R) is an easy to handle, air-stable and powerful electrophilic fluorination agent that can be used in a novel oxidative Mannich-type carbon-carbon bond forming process to allylate electron deficient tertiary amines in moderate to good yields. This process is rapid, operationally simple, insensitive to atmospheric conditions and of potentially broad use, especially in the construction of homoallylamines. (C) 2011 Elsevier Ltd.

在简单的耐空气无机盐K 3 PO 4的催化下,已使用各种羧酸作为偶联剂构建了伯/仲胺直接N-单/二烷基/氟烷基化的可扩展方案。有利的特征包括100种实例,10种药物和类药物胺,氟化复杂的叔胺,克级合成和同位素标记胺,因此证明了该方法在工业上的潜在适用性。与减少酰胺中间体所需的传统反应性金属氢化物或硼氢化物相比,反应性较小的氢化硅的参与可能有助于显着的官能团相容性。
