  Efficient synthesis of functionalized 6-arylsalicylates via microwave-promoted Suzuki cross-coupling reaction

  摘要：

  Functionalized 6-arylsalicylate substructures occur in a variety of pharmacologically relevant natural products and bioactive compounds. They are also broadly used as important intermediates in organic synthesis. Traditional synthetic methods have suffered from some drawbacks, such as relatively harsh reaction conditions, narrow range of substrates, and poor yields. Utilizing microwave irradiation, the synthesis of functionalized 6-arylsalicylates via a Suzuki cross-coupling has been developed with a wide range of substrates. Almost all the reactions proceeded smoothly and afforded moderate to excellent yields of products, which indicated that electronic effects and steric modifications have little effect on this reaction.

• Synthesis of Functionalized Biaryls Based on a Heck Cross-Coupling-[3+3] Cyclization Strategy

  日期：——

  6-Arylsalicylates were regioselectively prepared by formal [3+3] cyclization of 1,3-bis(silyloxy)-1,3-butadienes with 1-aryl-3-ethoxyprop-2-en-1-ones which are available by Heck reaction of benzoyl chlorides with ethylvinyl ether. In this context, the first [3+3] cyclizations of brominated substrates are reported.

  The formal [3+3] cyclization of 1,3-bis(silyloxy)buta-1,3-dienes with 1-aryl-3-ethoxyprop-2-en-1-ones, available by Heck reaction of benzoyl chlorides with ethyl vinyl ether, afforded a variety of 6-arylsalicylates. The reaction of the products with concentrated sulfuric acid resulted in the formation of fluorenones. 6-Alkylsalicylates were prepared by cyclization of 1,3-bis(silyl­oxy)buta-1,3-dienes
