Preparation of Vitamin A1 Retinol

  • Synthetic
    There are many synthetic routes for retinol and its derivatives, the common one is the Isler route, namely C13-C14-C20.

    Citral and acetone undergo aldol condensation under alkaline conditions to obtain pseudoionone, which is cyclized under the action of sulfuric acid to become ionone, of which β-ionone is C13 referred to in the route. C13 was condensed by Darzens to obtain glycidyl ester, and then hydrolyzed, decarboxylated and rearranged to obtain C14 aldehyde. It is then condensed with Grignard reagent prepared from C6 alcohol to obtain C20, which is the main chain of retinol. After a series of rearrangements, you end up with retinol.
