## Abstract The combination of Ga(OTf)~3~ with chiral semi‐crown ligands (**1a**–**e**) generates highly effective chiral gallium Lewis acid catalysts for aqueous asymmetric aldol reactions of aromatic silyl enol ethers with aldehydes. A ligand‐acceleration effect was observed. Water is essential f
