A water-mediated and Rh-catalysed one-pot multi-stepsynthesis of chiral 1,3-diarylpropan-1-ols is presented. This protocol utilizes readily available terminal alkynes and aldehydes as reaction partners, and features mild conditions, easy operation and water as the sole solvent, thus serving as an ideal means for the efficientsynthesis of chiral 1,3-diarylpropan-1-ols. Control experiments suggested
