Stereoselective Synthesis and Thermal Behavior of (Z)-Epoxyhexenynes: A Sinple and General Route to 2-Vinylfurans

Abstract
An efficient approach for the synthesis of 2,3-disubstituted furans (2a-j/3a-j) is described by using the thermally induced rearrangement of epoxyhexenynes (1a-j) which are prepared by stereoselective synthesis of the (Z)-pentenynals 10 and subsequent Darzens reaction.
