Chemistry is an experimental science, and the best way to enjoy it and learn about it is performing experiments. name: Furan-2,4(3H,5H)-dione. Introducing a new discovery about 4971-56-6, Name is Furan-2,4(3H,5H)-dione

Cyclobutanes derived from [2+2] photocycloaddition reactions of tetronic acid esters were subjected to free-radical fragmentation reactions. The product formation was strongly dependent on the relative stabilities of the intermediate radicals, thus leading to either an oxepane or a methylenetetrahydrofuran in good yields.

A new approach has been developed for construction of the western and eastern lactams, e.g. 2 and 3, needed for synthesis of isobacteriochlorins. It involves acylation of pyrroles with lactonic acids to form ketones. These are then efficiently converted into the desired lactams by a short sequence of reactions. All the steps are high yielding and simple to carry out.

Application of 1679-47-6, Chemistry is the science of change. But why do chemical reactions take place? Why do chemicals react with each other? The answer is in thermodynamics and kinetics.In a document type is Article, and a compound is mentioned, 1679-47-6, 3-Methyldihydrofuran-2(3H)-one, introducing its new discovery.

A series of gamma-butyrolactones and gamma-thiobutyrolactones possessing a variety of alkyl groups and alkyl-substitution patterns was prepared and evaluated for anticonvulsant and convulsant activity. Behavioral studies performed on these compounds suggest that maximal anticonvulsant activity (against maximal electroshock and pentylenetetrazol) results when three or four carbon atoms are present at the alpha-position. For convulsant potency, a similar dependence on the size of the alkyl chain at the beta-position was observed. Additional gamma-dimethyl groups were found to increase the convulsant potency of a beta-substituted compound and to cause an an alpha-substituted anticonvulsant to become a convulsant. In general, sulfur for oxygen heteroatom substitution in the alpha-substituted lactones resulted in improved anticonvulsant potency and spectrum of activity. Binding of these compounds to the picrotoxin site of the GABA receptor complex was demonstrated with a [35S]-tert-butylbicyclophosphorothionate radioligand binding assay. Measurements of brain concentrations for selected compounds supports a hypothesis that correlates binding to the picrotoxin site with the pharmacological effects of these compounds.
