Utility of 1-(2,4-dimethoxyphenyl)-3-aryl-prop-2-ene-1-ones as ring transformer in preparing heterocyclic compounds and their potential biological activities

As an effort to synthesize new heterocyclic compounds, which would be expected to have a pharmacological and biological activities, we report here the reactivity of 1-(2,4-dimethoxyphenyl)-3-aryl-2-propen-1-ones (Ia&b), as Michael acceptors under differen

Investigations on the Hydrolytic Stability of 4-Arylmethylidene-2-pyrazolin-5-ones

The 4-Arylmethylidene-2-pyrazoline-5-ones S are not stable under aqueous alkaline conditions.By the substitution of R3 with electron donor substituents S reacts preferably yielding aldehyde A and 2-pyrazoline-5-one P, while with electron acceptor substituents S forms 4,4'-arylmethylidene-bis-2-pyrazoline-5-one B.The intermediate of hydrolysis is 4-(arylhydroxymethyl)-2-pyrazoline-5-one SOH.The second order rate constants of the reactions of S with hydroxidions and with 2-pyrazoline-5-ones P(-) are determined.The dependence of the hydrolytic decomposition of S on the pH value, substituents and temperature is suitable for the intermediate formation of SOH.
