✦ Synopsis
1‐Lithiumoxy‐2‐buten‐2‐yl‐lithium and 1‐lithiumoxy‐2‐buten‐3‐yl‐lithium, both as pure (Z)‐stereoisomers, are easily obtained by halogen/metal exchange between s‐butyllithium and (E)‐2‐bromo or (E)‐3‐bromo 2‐buten‐1‐ol, respectively. The starting materials are readily available through dehydrobromination of threo‐2, 3‐dibromo 1‐butanol. The new organolithium compounds are useful intermediates for the preparation of configurationally homogeneous, specifically substituted and branched alkenols.
