合成路线1
该中间体在本合成路线中的序号:(IV)Indanone derivative (II) was obtained as the major product from the ozonolysis of vitamin D3 (I). Horner-Emmons condensation of ketone (II) with trimethyl phosphonoacetate (III) provided the unsaturated ester (IV). This was finally hydrolyzed to the corresponding carboxylic acid by treatment with LiOH.
