Synthesis of (Z)-trisubstituted olefins with all substituents different from methyl via α,β-disubstituted (E)-acroleins

Article abstract of DOI:10.1007/BF02495562

(E)-2,3-Disubstituted allyl bromides readily accessible in two steps from the corresponding enals react with dialkyl cuprates in a high regio-and stereoselective fashion to give (Z)-trisubstituted olefins with all substituents different from methyl. This
