  A convenient synthetic route to furan esters and lactones by palladium-catalyzed carboalkoxylation or cyclocarbonylation of hydroxyl-substituted 3-iodofurans

  摘要：

  An effective palladium-catalyzed protocol for the intermolecular carboalkoxylation or intramolecular cyclocarbonylation of hydroxyl-substituted 3-iodofurans under carbon monoxide pressure has been developed. The 3-iodofurans are readily prepared by iodocyclization of 2-(1-alkynyl)-2-alken-1-ones in the presence of various diols. (C) 2010 Elsevier Ltd. All rights reserved.

  Solution-Phase Synthesis of a Highly Substituted Furan Library

  摘要：

  A library of furans has been synthesized by iodocyclization and further diversified by palladium-catalyzed coupling processes. The key intermediate 3-iodofurans have been prepared by the electrophilic iodocyclization of 2-iodo-2-alken-1-ones in the presence of various nucleophiles in good to excellent yields under mild reaction conditions. These 3-iodofurans are the key components for library generation through subsequent elaboration by palladium-catalyzed processes, such as Suzuki-Miyaura, Sonagashira, Heck, aminocarbonylation, and carboalkoxylation chemistry to afford a diverse set of 2,3,4,5-tetrasubstituted furans.

  Highly substituted lactone- and ester-containing furans have been prepared by the efficient palladium-catalyzed intramolecular cyclocarbonylation or intermolecular carboalkoxylation, respectively, of hydroxyl-containing 3-iodofurans, readily prepared by the iodocyclization of 2(1-alkynyl)-2-alken-1-ones in the presence of various diols.
