Synthetic Route of 23190-16-1. Let¡¯s face it, organic chemistry can seem difficult to learn. Especially from a beginner¡¯s point of view. Like 23190-16-1, Name is (1R,2S)-(?)-2-Amino-1,2-diphenylethanol. In a document type is Patent, introducing its new discovery.
Ca valve 2 Symmetry diphenylamine type chiral bisoxazoline ligand as well as synthesis method and application thereof (by machine translation)
The invention discloses a C as shown 3 in a formula I. a valve 2 Symmetric diphenylamine type chiral bisoxazoline ligand, synthesis method and application thereof in asymmetric catalytic reaction. The ligand is removed by introducing different groups on the diphenylamine skeleton. a valve 2 Symmetry, realizes the accurate regulation and control of ligand skeleton ‘electron effect’. The compound is prepared from the compound represented by the formula shown in the formula shown in the formula 1 I by using an ortho-aminobenzoic acid 4 derivative and an o-chlorobenzoic acid derivative as a 2 starting raw material, and then reacted with the chiral amino alcohol compound shown in the 3 formula I to obtain the compound [beta]-bishydroxyamide represented by the formula (I). a valve 2 -symmetric diphenylamine type chiral bisoxazoline ligand. The invention also provides a use of the de-C. a valve 2 Use of a symmetric diphenylamine type chiral bisoxazoline ligand in an asymmetric catalytic reaction with a catalyst formed by coordination of a copper salt, a zinc salt, a nickel salt, an iron salt or a rhodium salt.
