Dynamickineticresolution of various homoallylic alcohols with the use of Candidaantarcticalipase B and ruthenium catalyst 2 afforded homoallylic acetates in high yields and with high enantioselectivity. These enantiopure acetates were further transformed into homoallylic acrylates after hydrolysis of the ester function and subsequent DMAP‐catalyzed esterification with acryloyl chloride. After ring‐closing
