Synthesis of δ-Ketonic and δ-Thioacetalated Phosphonium Salts and Their Use in Wittig Reactions for Carbonyl n+4 Homologation

The δ-thioacetalated phosphonium salts 4 are obtained by addition of triphenylphosphine on cyclopropylketones 2 followed by carbonyl thioacetalization.The corresponding ylides are converted into 2-(3'-alkenyl)-1,3-dithianes 6 with predominant Z-stereochem
