O-Acetyl 1,3-propanediol serves as an acrolein proelectrophile in π-allyliridium-C,O-benzoate-catalyzed carbonyl allylations mediated by racemic α-substituted allylic acetates. Using the iridium catalyst modified by (R)-SEGPHOS, a variety of 3-hydroxy-1,5-hexadienes are formed with uniformly high levels of regio-, anti-diastereo-, and enantioselectivity.
