Applicazioni

Diethyl diallylmalonate is the starting material for enantioselective synthesis of carbocyclic nucleoside analogues. It is also used as Low catalyst loading in ring-closing metathesis reaction. Cationic nickel (with monodentate phosphoramidites and Wilke?s azaphospholene as ligands) catalyzed cycloisomerisation of diethyl diallylmalonate has been reported.

Note

Store under cool dry place. Ensure good ventilation.
