应用
Ethyltriphenylphosphonium bromide acts as a reactant in the synthesis of D-amino acids from L-cysteine-derived thiazolidines, Leiodolide A through aldol reactions and Horner-Wadsworth-Emmons olefination. It is also used in the preparation of cycloalkanoindolines through diastereoselective intramolecular inimo-ene reactions. Further, it is used as a reagent in solid-state metathesis polycondensation to prepare alkyl-dipropenylthiophene monomers and Mizoroki-Heck cyclization and cascading Tsuji-Trost cyclization reactions.

备注
