The transformation below does not takes place when the starting materials are mixed with a thermodynamic base, alcoholic solvent and acidic workup. Why? When the starting material below is first mixed with sodium cyanide, then thermodynamic base, alcoholic solvent and acidic workup, the product forms quickly and in large amounts. Why?
