synthesis\u003c\/strong\u003e. These chiral N,N'-dioxide compounds overcome the traditional requirement for highly rigid ligand frameworks. Much like a pair of \u003cstrong\u003enunchaku\u003c\/strong\u003e, 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.\u003c\/p\u003e\n\u003ch2\u003eApplication:\u003c\/h2\u003e\n\u003cp\u003e\u003cstrong\u003eAsymmetric Catalysis\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003e\u003ch2\u003eRelated articles\u003c\/h2\u003e\u003c\/li\u003e\n\u003cli\u003e\u003ca target=\"_blank\" href=\"https:\/\/www.jk-sci.com\/blogs\/innoportal\/fengs-chiral-nitroxide-ligand-can-efficiently-realize-more-than-50-asymmetric-catalytic-reactions\"\u003eFeng's chiral nitroxide ligand: can efficiently realize more than 50 asymmetric catalytic reactions\u003c\/a\u003e\u003c\/li\u003e\n\u003cli\u003e\u003ca target=\"_blank\" href=\"https:\/\/www.jk-sci.com\/blogs\/innoportal\/scientific-research-achievements-of-academician-feng-xiaoming-fengs-chiral-dinitroxide-ligand-catalyst-strong-broad-spectrum-and-good-stereoselectivity\"\u003eChiral Dinitroxide Catalysts: A Breakthrough in Asymmetric Synthesis by Professor Feng Xiaoming\u003c\/a\u003e\u003c\/li\u003e\n\u003c\/ul\u003e\n    \u003c\/div\u003e\n    \n\n    \u003c!-- Faq --\u003e\n    \n    \u003ch2 class=\"section-header\"\u003eFAQ\u003c\/h2\u003e\n    \u003cdiv class=\"html-area\"\u003e\n        \u003cp\u003e\u003cstrong\u003eWhat is NO-Feng-PDPhMPPr used for?\u003c\/strong\u003e\u003cbr\u003eNO-Feng-PDPhMPPr is primarily used as a \u003cstrong\u003echiral N,N'-dioxide ligand\u003c\/strong\u003e in asymmetric catalysis.
