molecules with novel skeletons, but also to identify the enzymes that catalyze diverse chemical reactions. Exploring the substrate promiscuity and catalytic mechanism of those biosynthetic enzymes facilitates the development of potential biocatalysts. SfaB is an acyladenylate‐forming enzyme that adenylates a unique building block, 3‐isocyanobutanoic acid, in the biosynthetic pathway of the diisonitrile
promote the FeCl2-catalyzed N-amidation reaction of arylamines with dioxazolones leading to hydrazides in high efficiency and chemoselectivity. The new ligand-promoted N-amidation protocols offer a convenient way to access various challenging triazane compounds via double or sequential N-amidation of primary arylamines.
大体积烷基膦 (P t Bu 3 ) 可以将角色从参与者配体转换为旁观者配体,以促进 FeCl 2催化的芳胺与二恶唑酮的N酰胺化反应,从而高效且具有化学选择性地生成酰肼。新的配体促进的N -酰胺化方案提供了一种通过伯芳胺的双重或连续N -酰胺化来获得各种具有挑战性的三氮烷化合物的便捷方法。
