Nitrile synthesis
Webb5 We recently demonstrated a high-yielding prebiotic synthesis of phosphoserine nitrile Sep-CN33, so we next investigated Ac-Dha-CN synthesis via phosphate elimination. Acetylation of Sep-CN in water with AcSH and ferricyanide at pH 7 yielded Ac-Sep-CN (80%) after 1 h. Phosphoserines typically require alkaline pH Webb30 mars 2024 · Nitrile Synthesis from aldehyde within various technique. Inspired by this, we chose hydroxylamine as the nitrogen source for nitrile synthesis. The alpha effect of the hydroxyl group converts the amine group of hydroxylamine into a strong nucleophile, leading to the rapid formation of nitrile.
