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.

methodology concerning the Pd(II)-catalyzed intermolecular difunctionalization of conjugateddienes is reported to synthesize a series of functionalized morpholines and 2-morpholones. Widely distributed and easily obtained β-amino alcohols and α-amino acids, as starting nitrogen and oxygen sources, are successfully applied in the difunctionalization of conjugateddienes respectively. The majority of the desired
defluorinative functionalization of two C(sp3)-F bonds in a CF3 group. Various attractive monofluoroalkene-masked medium-sized heterocyclic lactams and lactones are obtained in moderate to excellent yields. Simple derivation of these masked-heterocycles efficiently affords useful skeletons of lactams, lactones, and 1,4-oxazepanes in a single diastereoisomer. Mechanism studies indicate that a unique sequential
