α,β-Unsaturated 2-acyl imidazoles are a novel and practical class of dienophiles for the DNA-based catalytic asymmetric Diels-Alder reaction in water. The Diels-Alder products are obtained with very high diastereoselectivities and enantioselectivities in
Ligand denticity controls enantiomeric preference in DNA-based asymmetric catalysis

DNA-based catalysis can be used to control the enantioselectivity of copper-catalysed Diels-Alder and Friedel-Crafts reactions to produce either enantiomer of the product by changing the denticity of the ligand coordinated to the Cu(ii) ion, even though t

Here we found that the enantioselectivity of G-quadruplex DNA-based Diels-Alder reaction can be switched by just changing Na+ to K +, which is ascribed to the structural transformation of the G-quadruplex from antiparallel to hybrid-

A triazacyclophane (TAC) scaffold decorated with three histidine amino acid residues was used as a tridentate ligand in asymmetric copper(II)-catalysed Diels-Alder and Michael addition reactions in water. Enantiomeric excesses up to 55 % were obtained in
