Description
Summary:We describe the application of an amidoxime as catalyst in the synthesis of homoallylic alcohols from the allylation reaction of aldehydes with different features using potassium allyltrifluoroborate. The reaction was conducted with a catalytic amount of the appropriate amidoxime in a biphasic system (water:dichloromethane), open atmosphere and ambient temperature. The products were obtained in yields ranging from moderate to excellent in short reaction times without the need for further purifications for almost all examples. Additionally, the reaction has proved chemo- and regioselective.
