Alkenes as Chelating Groups in Diastereoselective Additions of Organometallics to Ketones
[Image: see text] Alkenes have been discovered to be chelating groups to Zn(II), enforcing highly stereoselective additions of organozincs to β,γ-unsaturated ketones. (1)H NMR studies and DFT calculations provide support for this surprising chelation mode. The results expand the range of coordinatin...
