O-Unprotected keto-and aldoximes are readily C-allylated with allyl diisopropyl boronate in the presence of arylboronic acid catalysts to yield highly substituted N-α-secondary and tertiary homoallylic hydroxylamines. The method was used in the total synthesis of the trace alkaloid N-Me-Euphococcine.

-
Paragraph 0066 - 0069, (2016/11/21)
The invention provides a novel chiral phosphine ligand, a metal catalyst containing the chiral phosphine ligand and a preparation method and an application thereof. The novel chiral phosphine ligand has a structural formula shown in the attached figure; the metal catalyst is a transition metal complex which is synthesized by the novel chiral phosphine ligand and transition metal, and is used for asymmetric catalyzing and hydrogenating reaction, and catalyzing and hydrogenating to synthesize beta-arylamide with high optical purity. The novel chiral phosphine ligand has the advantages that the economic practicality is higher, the product purity is high, the carrying amount of ligand (S/C) is high, and the like.
