General description

Dimethyl malonate undergoes enantioselective palladium-catalyzed allylic substitution reaction with 1,3-diphenylprop-2-enyl acetate to yield diastereomeric pure thienylpyridines.

Application

Dimethyl malonate was used in gold catalyzed oxidative esterification of glycerol, 1,2-propanediol and 1,3-propanediol.
