A method for the synthesis of difficult-to-access amides was developed through the coupling of stericallyhindered carboxylic acids and electron deficient amines via SO2F2-mediated dehydration. The method feathers with broad substrate scope, mild conditions, excellent functional group compatibility and high yields.
通过空间受阻的羧酸和缺电子的胺通过SO 2 F 2介导的脱水的偶联,开发了一种难以合成的酰胺的合成方法。该方法具有广泛的底物范围,温和的条件,优异的官能团相容性和高收率。
