difficult to obtain 1,3,4′-tricarbonyl compounds through a water mediated, TBAF·3H2O promoted unprecedented tandem reaction of 1,2-allenic ketone with α-halo ketone or α-halo ester has been developed. Remarkably enhanced reactivity and improved chemoselectivity by using water as the reaction medium was observed. The 1,3,4′-tricarbonyl compounds facilitate further versatile transformations, which underscores
通过水介导的TBAF·3H 2 O有效高效地合成原本难以获得的1,3,4'-三羰基化合物,促进了1,2-烯酮与α-卤代的空前串联反应酮 或α-halo 酯已经被开发出来。通过使用,显着增强了反应性并改善了化学选择性水观察到反应介质。1,3,4'-三羰基化合物促进了进一步的通用转化,这突显了这些产物作为合成中间体的重要性。
