Descrição geral

Yu Borylation Ligand, also referred to as 2,4-dimethoxyquinoline, has been developed by Professor Jin-Quan Yu and coworkers. 2,4-dimethoxyquinoline can be prepared by reacting 2,4-dichloroquinoline with sodium methoxide.

Aplicação

The Yu Borylation Ligand in tandem with bis(pinacolato)diboron (Aldrich 473294) under palladium catalysis can promote direct borylation of C(sp3)-H bonds. Yu and coworkers have displayed this on both alanine-derived amides and cyclopropanes with directing group assistance from the Yu-Wasa Auxiliary (Aldrich 791806).
Yu Borylation Ligand (2,4-Dimethoxyquinoline) may be used as a starting reagent in the synthesis of 2,4 -dimethoxy-3-(3methylbut-2-enyl)quinoline and 4-methoxy-1H-quinolin-2-one. It may also be used in the preparation of isoprenyl derivatives.
