Viala,Munier,Santelli
, p. 3347 - 3352 (1991)
Total synthesis of three sex pheromone components including an all-cis diene or triene unit are described. Starting from decanal, cis-Wittig reactions, by using C3 homologating agent 4 and convenient phosphonium salts, allowed us to built up all-cis skipp
Synthesis of δ-Ketonic and δ-Thioacetalated Phosphonium Salts and Their Use in Wittig Reactions for Carbonyl n+4 Homologation
Cristau, Henri-Jean,Beziat, Yves,Niangoran, Claude Ekissi,Christol, Henri
, p. 648 - 651 (2007/10/02)
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
