NO-Feng-PDEtPPi, L-PiEt2, 95%

Product Introduction

N,N'-Dioxides (Bis-N-oxide Compounds) are an ideal class of ligands and catalysts for asymmetric synthesis. These chiral N,N'-dioxide compounds overcome the traditional requirement for highly rigid ligand frameworks. Much like a pair of nunchaku, they combine rigidity and flexibility, allowing precise control over how reactants approach and interact during a chemical reaction. By directing the orientation and encounter of reaction partners, these ligands help ensure that chemical bonds are formed in the desired manner, resulting in high catalytic efficiency and excellent enantioselectivity.
