A Scalable L‐α‐Glycerophosphorylcholine Synthesis through the Automatic pH‐Controlled (R)‐Glycidol Ring Opening with Phosphorylcholine

open access: yesChemistry–Methods, EarlyView.
Automatic titrator enables the regioselective ring opening of (R)‐glycidol in water in the presence of phosphorylcholine, leading to the synthesis of L‐α‐glycerophosphorylcholine, a commercially available drug, in very high yield. The reaction is triggered by a minimum amount of NaOH and reactants, while the optimal pH is precisely regulated through ...
