Gupton, John T. published the artcileReaction of Gold’s reagent with activated methylene groups derived from esters and nitroarenes, Application of Ethyl 3-(dimethylamino)acrylate, the publication is Synthetic Communications (1982), 12(12), 939-46, database is CAplus.
Acetate and malonate esters reacted with Me2NCH:NCH:N+Me2 Cl– (I) to yield RC(:CHNMe2)CO2Et (R = H, Ph, CO2Et, cyano). Similarly prepared, from nitrotoluenes and lactones, were II (R = H, Br, Cl, NO2; R1 = NO2, H) and III (R = H, Me). Thus, PhCH2CO2Et was treated with I and NaOEt in EtOH to give PhC(:CHNMe2)CO2Et.
Synthetic Communications published new progress about 924-99-2. 924-99-2 belongs to esters-buliding-blocks, auxiliary class Alkenyl,Amine,Aliphatic hydrocarbon chain,Ester, name is Ethyl 3-(dimethylamino)acrylate, and the molecular formula is C7H13NO2, Application of Ethyl 3-(dimethylamino)acrylate.
