4-Phenyl-3-buten-2-ol can be used as reagent/reactant for rhodium-catalyzed dynamic kinetic enantio-, chemo- and regioselective allylation of phenols/naphthols/hydroxypyridines with allylic carbonates. It can also be used in biological study for comparative study on quality of soy sauce produced from whole soybeans and defatted soybeans.
