Application of the Horner−Wadsworth−Emmons olefination in the construction of E‑α,β-unsaturated β‑boryl nitrilesGosak, Kaja (Avtor) Črnugelj, Martin (Avtor) Časar, Zdenko (Avtor) olefinationboryl nitrilesdifferential scanning calorimetryisolationmixturesstereoselectivityHerein, we describe a simple transition-metal-free synthesis of E-α,β-unsaturated β-boryl nitriles by the Horner−Wadsworth−Emmons reaction starting from potassium acyltrifluoroborates. The methodology encompasses a broad range of alkyl and aryl substrates. The reaction conditions are simple, and the reaction products are in most cases isolated with good yields as pure E isomers without column chromatography.20252025-12-03 11:53:30Članek v reviji176540sl
