参考标题:Five- And Six-Membered Nickelacyclic Carboxylates As Reagents For The Facile Synthesis Of δ-Ketocarboxylic Acids, Isocoumarins, And 1,3-Dicarbonyl Derivatives Of Benzoic Acid 作者:Dirk Walther,Jens Langer,Martin Gärtner,Helmar Görls |发布日期:2006.8 摘要:The Nickelacyclic Carboxylates A And B Reacted With î+/--Halo Ketones To Form î+/-,î²-Unsaturated î´-Ketocarboxylic Acids Which Were Easily Converted Into Pyranones Or Isocoumarins. In Addition, Reaction Of The Nickelacyclic Acyl Derivative C With î+/--Halo Ketones Resulted In The Formation Of Substituted 1,3-Dicarbonyl Compounds With A Benzoic Acid Substituent In The 1-Position. In These Reactions, Many Functional Groups Were Tolerated.
