The condensation of the acetals of acetophenone and acetaldehyde with enol ethers, as a result of which 2- and 3-phenyl-1,1,3-trialkoxybutanes were obtained, was studied.The acid hydrolysis of the products leads to the formation of 2- and 3-phenylbutenals, from which 2- and 3-phenyl-1-trimethylsilyloxy-1,3-butadienes were obtained by the action of trimethylchlorosilane and triethylamine.The reaction of the silyloxydienes with ethyl orthoformate in the presence of zinc chloride as catalyst gave the monoacetals of α- and β-phenylglutaconaldehydes, which were converted into the corresponding bisacetals by the further action of the orthoformate.
