Enzymes are biological catalysts that produce large increases in reaction rates and tend to be specific for certain reactants and products. 72-48-0, Name is 1,2-Dihydroxy-9,10-anthracenedione, molecular formula is C14H8O4, belongs to indole-building-block compound. In a document, author is Yu, Haifeng, introduce the new discover, Name: 1,2-Dihydroxy-9,10-anthracenedione.
An efficient and highly regioselective synthesis of isomeric 3-[1-substituted pyrazol-3(5)-yl]indoles has been developed by the acid-mediated regioselective cyclocondensation reaction of beta-ethyltho-beta-indolyl-alpha,beta-unsaturated ketones and monosubstituted hydrazines. In the presence of 1 equivalent of AcOH in refluxing EtOH, the cyclocondensation reaction of beta-ethyltho-beta- indolyl-alpha,beta-unsaturated ketones with monosubstituted hydrazines yielded 3-(1-substituted pyrazol-5-yl)indoles in excellent yields, while 3-(1-substituted pyrazol-3-yl)indoles were obtained in good yields when the cyclocondensation reaction was carried out in refluxing AcOH.
Balanced chemical reaction does not necessarily reveal either the individual elementary reactions by which a reaction occurs or its rate law. In my other articles, you can also check out more blogs about 72-48-0. Name: 1,2-Dihydroxy-9,10-anthracenedione.
