α,β-Unsaturated amides play a vital role in natural products, pharmaceuticals, organic synthesis, and functional materials. Herein, we disclosed a regio- and stereoselective hydroaminocarbonylation of unsymmetrical internal alkynes via palladium catalysis to synthesize α,β-unsaturated amides. This protocol features excellent regio- and exclusive (E)-stereoselectivity, high atom and step-economy, broad
α,β-不饱和酰胺在天然产物、药物、有机合成和功能材料中发挥着至关重要的作用。在此,我们公开了通过钯催化对不对称内炔烃进行区域选择性和立体选择性氢化氨基羰基化合成 α,β-不饱和酰胺。该协议具有出色的区域和排他 ( E ) 立体选择性、高原子和阶梯经济性、广泛的底物范围和官能团耐受性。
