Porter, Jacob published the artcileA novel, unusual acid catalyzed route to substituted 1,4-dihydropyridine via double decarboxylation, HPLC of Formula: 924-99-2, the publication is Letters in Organic Chemistry (2011), 8(9), 610-613, database is CAplus.
A simple and high yield route to 3,4,5-trisubstituted 1,4-dihydropyridine systems via an interesting intermol. condensation and double decarboxylation is described. Thus, in presence of AcOH, reaction of (E)-EtO2CCH:CHNHBn and di-Et (ethoxymethylene)malonate gave 1,4-dihydropyridine derivative (I).
Letters in Organic Chemistry 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, HPLC of Formula: 924-99-2.
