  A Facile Zr-Mediated Approach to (Z)-Enynols and Its Application to Regio- and Stereoselective Synthesis of Fully Substituted Dihydrofurans

  摘要：

  [GRAPHICS]Efficient synthetic approaches to stereodefined (Z)-enynols have been developed through zirconium-mediated cross-coupling reactions of three different components involving alkyne, ketone, and alkynyl bromide in a one-pot procedure. The subsequent electrophilic cyclization of a wide variety of (Z)-enynols affords fully substituted (Z)-5-(1-iodoylidene)2,5-dihydrofurans with high regio- and stereoselectivity under mild reaction conditions.

  A highly efficient carbon-carbon triple bond cleavage reaction of (Z)-enynols was developed, which offered a new route to highly substituted butenolides. The methodology is realized by a tandem reaction using a single gold(I) catalyst, which could catalyze different reactions of cyclization/oxidative cleavage in the same vessel.
