  Design, Synthesis, and Diversification of 3,5-Substituted Enone Library

  摘要：

  This paper describes the synthesis of a 300 member library of 3,5-substituted enones. The synthesis starts with 6 different bromoenones that are accessed from the corresponding 1,3 diones. These bromides are then diversified by Suzuki coupling with a variety of aromatic and vinyl boronic acids. Additionally a small series of triazoles was synthesized by a Sonogashira coupling reaction dipolar cycloacklition sequence. The library was analyzed by principal component analysis to examine its diversity.

• Palladium-Catalyzed Decarboxylative Coupling of Alkynyl Carboxylic Acids and Alkenyl Tosylates for the Synthesis of Enynones

  A palladium-catalyzed decarboxylative coupling reaction was developed for the synthesis of 3-(1-alkynyl)-2-cyclohexen-1-ones. A variety of alkynyl carboxylic acids were coupled with 3-oxocyclohexenyl tosylates to afford the corresponding enynones in good to excellent yields. The developed catalytic system is phosphine free and showed good tolerance toward various functionalities such as chloride, cyano

  3 and 4, whereas, under these conditions, 3‐(alk‐1‐ynyl)cyclohex‐2‐enones 5 give only one cyclobutane adduct 6 regio‐ and diastereoselectively. In contrast, 3‐(alk‐1‐ynyl)‐2‐methylcyclohex‐2‐enones 10 undergo [2+2]‐cycloaddition to the same diene exclusively at the C≡C bond to afford hitherto unknown 3‐cyclobutenylcyclohex‐2‐enones 11.

  上照射，在2,3-二甲基丁-1,3-二烯的存在下，萘-2-酮1是定量和区域选择性转化成非对映异构环丁烷加合物的混合物3和4，而在这些条件下，3-（烷基-1-炔基）环己-2-烯酮5仅选择性地产生一个环丁烷和非对映体的环丁烷加合物6。相反，3-（alk-1-ynyl）-2-methylcyclohex-2-enones 10仅在C≡C键上与同一二烯进行[2 + 2]-环加成反应，从而提供迄今未知的3-cyclobutenylcyclohex-2-烯酮11。
