MECHANISMS OF REACTIONS OF 1,3-DICARBONYL COMPOUNDS WITH NUCLEOPHILIC REAGENTS. V. KINETICS OF ADDITION OF ALCOHOLS TO 4-AROYL-5-METHOXYCARBONYL-1-ARYL-2,3-DIHYDROPYRROLE-2,3-DIONES

The kinetics of the addition of water and of a series of alcohols to 4-aroyl-5-methoxycarbonyl-1-aryl-2,3-dihydropyrrole-2,3-diones were studied by a spectrophotometric method.The nucleophilic reactivity in the series of alcohols is determined by steric factors.The possibility of the occurrence of the reactions through cyclic transition states is discussed on the basis of an analysis of the dependence of the reaction rate on the structure of the reagents.
FIVE-MEMBERED 2,3-DIOXOHETEROCYCLES. V. SYNTHESIS OF 1-ARYL-4-AROYL-5-METHOXYCARBONYL-2,3-DIHYDRO-2,3-PYRROLEDIONES AND THEIR REACTIONS WITH WATER AND ALCOHOLS

1-Aryl-4-aroyl-5-methoxycarbonyl-2,3-dihydro-2,3-pyrrolediones were obtained from oxalyl chloride and methyl 4-aryl-2-arylamino-4-oxo-2-butenoates.They add water and alcohols reversibly with the formation of substituted 3,5-dihydroxy- and 5-alkoxy-3-hydro
