Chemistry, like all the natural sciences, begins with the direct observation of nature¡ª in this case, of matter.2915-53-9, Name is Dioctyl maleate, SMILES is O=C(OCCCCCCCC)/C=CC(OCCCCCCCC)=O, belongs to esters-buliding-blocks compound. In a document, author is Nikiforova, E. A., introduce the new discover, Application In Synthesis of Dioctyl maleate.
Reformatsky Reaction of 1-Aryl-3-(2-hydroxyphenyl)prop-2-en-1-ones with Methyl 1-Bromocyclohexanecarboxylate
1-Aryl-3-(2-hydroxy-5-R-phenyl)prop-2-en-1-ones reacted with the Reformatsky reagent derived from methyl 1-bromocyclohexanecarboxylate to give 4-(2-aryl-2-oxoethyl)-6-R-2H,4H-spiro[[1]benzopyran-3,1 ‘-cyclohexan]-2-ones. The products are formed as a result of intramolecular cyclization of the adduct of the organozinc reagent and substituted chalcone via nucleophilic attack of the phenoxide oxygen atom on the ester carbonyl carbon atom. No cyclization products resulting from attack of the enolate oxygen atom on the ester carbonyl carbon atom were detected.
Note that a catalyst decreases the activation energy for both the forward and the reverse reactions and hence accelerates both the forward and the reverse reactions. you can also check out more blogs about 2915-53-9. Application In Synthesis of Dioctyl maleate.
