摘要：
Hold me close: Highly enantioselective catalysis of tandem acetalization/cycloisomerization reactions of o-alkynylbenzaldehydes has been achieved using gold complexes of chiral acyclic diaminocarbene ligands that have electron-deficient aryl substituents. X-ray crystallography and DFT calculations implicate weak gold-arene interactions - absent in the case of simple phenyl substituents - that define the chirality of the substrate binding site.
