Herein a new synthetic route to 1,2-amino alcohols is presented by using C-H amidation of sp(3) methyl C-H bonds as a key step. Readily available alcohols were employed as starting materials after converting them to removable ketoxime chelating groups. Iridium catalysts were found to be effective for the C-H amidation, and LAH reduction was then used to furnish beta-amino alcohol products.
在本文中,通过使用sp(3)甲基CH键的CH酰胺化作为关键步骤,提出了一种合成1,2-氨基醇的新途径。在将现成的醇转化为可除去的酮肟螯合基团之后,将现成的醇用作起始原料。发现铱催化剂对于CH的酰胺化是有效的,然后将LAH还原用于提供β-氨基醇产物。
