We report a method for addition of α-bromophenylacetic acids to vinyl C-C bonds in styrenes to afford γ-lactones. Reactions employed a simple cobalt catalyst Co(NO3)2·6H2O in the presence of dipivaloylmethane (dpm) ligand.
Dynamic kinetic resolution of bis-aryl succinic anhydrides: Enantioselective synthesis of densely functionalised γ-butyrolactones

, p. 3231 - 3234 (2018/04/05)
The efficient Dynamic Kinetic Resolution (DKR) of disubstituted anhydrides has been shown to be possible for the first time. Using an ad hoc designed organocatalyst and an enantio- and diastereoselective cycloaddition process with aldehydes, stereochemically complex γ-butyrolactone derivatives can be obtained-with control over three contiguous stereocentres, one of which is all carbon quaternary.
Stereoarrayed 2,3-Disubstituted 1-Indanols via Ruthenium(II)-Catalyzed Dynamic Kinetic Resolution-Asymmetric Transfer Hydrogenation

, p. 2921 - 2924 (2018/05/28)
Activated racemic 2,3-disubstituted 1-indanones 1 possessing two stereolabile centers were stereoselectively reduced to the corresponding chiral 2,3-disubstituted-1-indanols 2 by ruthenium(II)-catalyzed dynamic kinetic resolution-asymmetric transfer hydro
Electrocarboxylation of alkynes with carbon dioxide in the presence of metal salt catalysts
Li, Chuanhua,Yuan, Gaoqing,Jiang, Huanfeng
experimental part, p. 1685 - 1689 (2011/07/07)
With some common metal salts (CuI, FeCl3) as catalysts, alkynes can be effectively electrocarboxylated with CO2 (4 MPa) in an undivided cell with Ni cathode and Al sacrificial anode containing n-Bu4NBr-DMF as supporting el
