  Synthesis of indenones via palladium-catalyzed annulation of internal alkynes

  摘要：

  A number of 2,3-disubstituted 1-indenones have been prepared in fair to good yields by treating o-iodo- or o-bromobenzaldehyde with various internal alkynes in the presence of a palladium catalyst. Synthetically, the methodology provides an especially convenient route to stable hindered indenones containing aryl, silyl, and tert-alkyl groups. The reaction is believed to proceed through a palladium-(IV) intermediate, and the regiochemistry of the reaction is controlled sterically.

  A new approach for the synthesis of indenone derivatives using I2-promoted cyclization of ortho-alkynylarylketones has been developed. This method provides a metal-free and convenient route for regioselective synthesis of indenones employing ortho-alkynylarylketones with predefined substituents to obtain indenone products in moderate to good yields.

  ambient temperature resulted in acid-promoted hydration and sequential intramolecular aldol condensation reactions to afford 3-aryl-1H-inden-1-one derivatives in good yields. The proposed reaction mechanism was strongly supported by the reaction behaviour of 4-chloro- and 5-methoxy-2-ethynylbenzophenone derivatives as substrates with Tf2NH, leading to the formation of the corresponding 3-aryl-1H-inden-1-ones

  efficient I-2-mediated approach to the synthesis of disubstituted indenones from readily available 2-alkynylbenzyl alcohols in the presence of H2O has been developed. These results are different from the known iodocyclization reactions in which O-containing heterocycles are obtained. (c) 2012 Elsevier Ltd. All rights reserved.
