An enantioselective Michael addition reaction of diphenylphosphine to substituted alkenylisoxazoles has been developed. The reaction proceeds efficiently under mild conditions with high yields (up to 99%) and moderate to excellent enantioselectivities (up to 92%) thus providing a hitherto unavailable direct access to a library of chiral tertiary phosphine‐functionalized isoxazoles.
