A catalytic method to synthesize 1,3,-dienes from propargylic precursors is reported. This palladium-catalyzed carbon-nitrogen bond-forming reaction furnishes 2-amino-1,3-dienes in excellent yields (up to 98%) and shows a broad tolerance to functional group diversity. The reaction has been demonstrated for over 30 amine substrates, including anilines and indoles, and proceeds under mild neutral conditions
报道了一种从炔丙基前体合成1,3,二烯的催化方法。钯催化的形成碳氮键的反应以极好的收率(高达98%)提供了2-氨基-1,3-二烯,并显示了对官能团多样性的宽容度。已证明该反应可用于30多种胺底物,包括苯胺和吲哚,并在温和的中性条件下进行。所得的1,3-二烯由于其进一步的反应潜力而具有很大的合成价值。
