<jats:title>Abstract</jats:title><jats:p>The intramolecular cyclopropanation of various <jats:italic>trans</jats:italic>‐allylic diazoacetates and alkenyl diazoketones has been achieved with excellent enantioselectivities of up to 98% <jats:italic>ee</jats:italic> and in quantitative yields by using a water‐soluble ruthenium(II)/hydroxymethyl(phenyl)oxazoline catalyst in a water/ether biphasic medium. The catalyst could be reused at least five times.</jats:p>
