Herein a new synthetic route to 1,2-amino alcohols is presented by using C-H amidation of sp(3) methyl C-Hbonds 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.
Directingstrategy has been extensively exploited to maintain activity and selectivity for the rapid access to functionalized molecules and pharmaceutical targets. However, ‘one‐to‐one’ activation model was usually achieved through traditional directingstrategy. Herein, we achieved ‘one‐to‐two’ activation model by slight modification of simple and practical ketoxime and amide functionality. With judicious

salicylic-aldehyde-derived L,X-type directing group with an electron-deficient 2-pyridone ligand to enable the β-methylene C(sp3 )-H arylation of aliphaticalcohols, which has not been possible previously. Notably, this protocol is compatible with heterocycles embedded in both alcohol substrates and aryl coupling partners. A site- and stereo-specific annulation of dihydrocholesterol and the synthesis of a key
