products has been developed by zinc-catalyzed intramolecular Conia-ene reactions of 1,3-dicarbonyl compounds with alkynes. This new route allows a wide range of dicarbonyl compounds, including the classically challenging 1,3-diesters and N,N′-disubstituted 1,3-keto amides, to be used for the Conia-ene reaction with inexpensive zinc chloride (ZnCl2) under neat conditions.
通过锌催化1,3-二羰基化合物与炔烃的分子内Conia-ene反应,已经开发出一种简单的,多用途的新方法,可将四元环变成六元环。这种新途径允许将广泛的二羰基化合物,包括经典的具有挑战性的1,3-二酯和N,N'-二取代的1,3-酮酰胺,用于与廉价氯化锌(ZnCl 2)。
