DNA-based asymmetric organometallic catalysis in water
Oelerich, Jens,Roelfes, Gerard
, p. 2013 - 2017 (2013)
Here, the first examples of DNA-based organometallic catalysis in water that give rise to high enantioselectivities are described. Copper complexes of strongly intercalating ligands were found to enable the asymmetric intramolecular cyclopropanation of α-diazo-β-keto sulfones in water. Up to 84% ee was achieved, in the presence of salmon testes DNA as the only source of chirality, using dipyrido[3,2-a:2′,3′-c]phenazine (dppz) derivatives as ligands.
A NEW FACILE SYNTHESIS OF α-DICARBONYL COMPOUNDS BY OXIDATION OF ALKYNES WITH Mo(VI) PEROXOCOMPLEX PROMOTED BY MERCURIC ACETATE

Mercuric acetate promoted oxidation of diaryl-, dialkyl-, and aralkylalkynes with (HMPA)MoO(O2)2 in 1,2-dichloroethane affords the corresponding α-diketones in good yields.Likewise, terminal alkynes can be converted into α-ketoaldehydes in excellent yields by using the same oxidizing system.
