Preparation of Retinyl acetate.

A method for the preparation of vitamin A acetate, comprising the steps of (1) condensation reaction between 3-methyl-4-oxo-2-buten-1-yl acetate (referred to as C5 aldehyde ester) and tetraethyl methylenediphosphonate under alkaline conditions to obtain the intermediate C6 phosphate ester (chemically named as 5-(diethyl phosphonate)-3-methyl-2,4-hexadien-1-yl acetate); (2) C6 phosphate ester was transposed under alkaline conditions and added to C14 aldehyde (chemically named 2-methyl-4-(2,6,6-trimethyl-1-cyclohexen-1-yl)-3-butene-1-aldehyde) in a Wittig-Horner condensation reaction to produce vitamin A acetate.
