On the Mechanisms of Enantioselective Reactions Using α,α,α′,α′ ‐Tetraaryl‐1,3‐dioxolane‐4,5‐dimethanol(TADDOL)‐Derived Titanates: Differences between C2‐ and C1‐symmetrical TADDOLs – facts, implications and generalizations

Abstract The titanates derived from α,α,α′,α′‐tetraaryl‐1,3‐dioxolane‐4,5‐dimethanols (TADDOLs, prepared from tartrate) act as catalysts for enantioselective additions of dialkylzinc compounds to aldehydes. For the standard reaction chosen for this investigation of the mechanism, the addition of die... View More
