Diethyl methylmalonate Usage And Synthesis
Chemical Properties    Clear liquid
Uses    Diethyl methylmalonate is used as intermediate for the syntheses of pharmaceuticals, e.g. non-steroidal anti-inflammatory agents with 2-acrylpropionic acid structures acrylpropionic acid structure. It is also used in the flavour and fragrance industries. Product Data Sheet
Uses    Diethyl methylmalonate was used to investigate the effect of direct supplementation of the medium with di-ester of methylmalonate on erythromycin fermentation in Saccharopolyspora erythraea mutB strain.
General Description    Diethyl methylmalonate reacts with 2-cyclohexenone under abnormal Michael conditions form 2-(3-oxocyclohexyl)-2-cyclohexenone. It causes the alkylation of poly(chloromethylstyrene) during pahse transfer catalysis.
