애플리케이션

The bicyclic, chiral phosphine was developed by the Kwon Research Group.Its initial applications were for asymmetric [3+2] annulation between allenes and imines as well as the first examples of phosphine-catalyzed asymmetric syntheses of 1,2,3,5-substituted pyrrolines. Along with nucleophilic organocatalysis, the P-chiral phosphines may also find utility in asymmetric transition-metal catalysis.

Two classes of phosphine-catalyzed addition/cycloaddition domino reactions of β'-acetoxy allenoate 1 have been developed. The reaction of 1 with 2-acyl-3-methyl-acrylonitrile 2 readily occurs to give 2-oxabicyclo[3.3.1]nonane 3, furnishing the β'-addition/[4 + 4] cycloaddition domino sequence. In this sequence, β'C of

In this study we performed the total synthesis of the terpene indole alkaloid (+)-ibophyllidine through a pathway involving asymmetric phosphine catalysis, with our novel l-4-hydroxyproline-derived chiral phosphine mediating the key [3 + 2] annulation. Hydrogenation of the [3 + 2]

We have prepared two new diastereoisomeric 2-aza-5-phosphabicyclo[2.2.1]heptanes from naturally occurring trans-4-hydroxy-L-proline in six chemical operations. These syntheses are concise and highly efficient, with straightforward purification. When we used these chiral phosphines as catalysts for reactions of γ-substituted allenoates with imines

Kwon Phosphines: P-Chiral Monodentate Phosphines from Hydroxyproline

Chiral phosphines have been the staple ligands for asymmetric transition metal catalysis and more recently operate as catalysts in organic phosphinocatalysis.
