A Petasis reaction of 2-pyridinecarbaldehydes with various amines and 4-substituted 1,2-oxaborol-2(5H)-ols was developed. In the presence of HCl, the reaction proceeded smoothly under very mild conditions and the corresponding desired products were obtained in medium to excellent yields. This method allows the access a wide range of highly functionalized allylic alcohols, which might be useful compounds
