Zirconium-Catalyzed Asymmetric Carboalumination of Unactivated Terminal Alkenes.

Accounts of chemical research

Xu S, Negishi EI.
PMID: 27685327
Acc Chem Res. 2016 Oct 18;49(10):2158-2168. doi: 10.1021/acs.accounts.6b00338. Epub 2016 Sep 29.

Carbometalation of alkenes with stereocontrol offers an important opportunity for asymmetric C-C bond formation. However, the scope of catalytic stereoselective carbometalation of alkenes had until recently been limited to electronically biased alkenes or those with the presence of directing...
