Descrição

Descrição geral

1,2-Bis[(2R,5R)-2,5-dimethylphospholano]benzene monooxide is a chiral ligand whose copper complexes are used extensively in many organic reactions such as addition to imines, nitroalkenes, and reduction of β,β-disubstituted vinyl sulfones.[1][2][3][4][5]

Aplicação

DuPhos and BPE Ligands: Highly Efficient Privileged Ligands

1,2-Bis[(2R,5R)-2,5-dimethylphospholano]benzene monoxide can be used:

• As a ligand in the preparation of dihydroquinolones and dihydroisoquinolones through palladium-catalyzed C-H functionalization of cyclopropane derivatives.[2]
• As an organocatalyst in the [4+1] annulation reactions of 2-enoylpyridine pyridine N-oxides[3] and olefins[4] with Morita-Baylis-Hillman (MBH) carbonates to yield dihydrofurans derivatives enantioselectively.
• As a ligand in the copper-catalyzed synthesis of chiral nitroalkanes via the addition of dialkylzinc to β-nitroalkenes.[5]
