functionality in chemical synthesis. Despite broad application of this transformation using aryl or vinyl electrophiles, there are few examples involving unactivated aliphatic substrates. Furthermore, there are no stereocontrolled aminocarbonylations of alkyl electrophiles known. Herein, we report a stereospecific aminocarbonylation of unactivated alkyl tosylates for the synthesis of enantioenriched amides
金属催化的氨基羰基化是在化学合成中安装酰胺官能团的标准方法。尽管使用芳基或乙烯基亲电体的这种转化得到了广泛的应用,但是很少有涉及未活化的脂族底物的例子。此外,还没有已知的烷基亲电体的立体控制的氨基羰基化。在此,我们报道了未活化的烷基甲苯磺酸盐的立体有择的氨基羰基化,用于合成对映体富集的酰胺。这种钴催化的转化过程使用了非常广泛的胺类,并具有出色的立体特异性和化学选择性。
