## Abstract (__S__)‐(1‐Benzylpyrrolidin‐2‐yl)diphenylmethanol and cinchonine were evaluated as promotors in the asymmetric additions of phenylacetylene to ketones, in order to prepare chiral propargylic alcohols. Good yields (up to 89%) and moderate enantioselectivities (up to 77.9% __ee__) were ac
