MOHTAT, Bita; AZIMZADEH, Setareh; DJAHANIANI, Hoorieh and PIRHADI, Leila. Ph3P catalyzed synthesis of alkyl 2-(4-oxopyridin-1(4H)-yl)acrylates by nucleophilic addition to alkyl propiolates. S.Afr.j.chem. (Online) [online]. 2010, vol.63, pp.204-206. ISSN 1996-840X.
4-Hydroxypyridine undergoes a smooth reaction with alkyl propiolates in the presence of triphenylphosphine to produce α and β-substituted alkyl acrylate products. When the reaction was performed with 4-hydroxyquinoline only α-substituted alkyl acrylates were obtained.
Keywords : 4-hydroxypyridine; 4-hydroxyquinoline; alkyl acrylates; alkyl propiolates; triphenylphosphine.
