Advanced Synthesis & Catalysis, 2020362, 2397-2418. (DOI: 10.1002/adsc.202000195)

Enantioselective reaction of water‐stable amido‐functionalized allylboronates with acetophenone derivatives in water is reported. The reaction was catalyzed with zinc hydroxide and a didecylamino‐functionalized chiral aminophenol reagent, affording a variety of homoallylic alcohols in up to 99% yield. The enantiomeric excess of the product reached up to 98%.
