Chemistry, like all the natural sciences, Formula: C7H10O4S, begins with the direct observation of nature¡ª in this case, of matter.6192-52-5, Name is 4-Methylbenzenesulfonic acid hydrate, SMILES is O=S(C1=CC=C(C)C=C1)(O)=O.[H]O[H], belongs to thiazines compound. In a document, author is Darehkordi, Ali, introduce the new discover.
An efficient ultrasonic-assisted synthesis of ethyl-5-(aryl)-2-(2-alkokxy-2-oxoethylidene)-7-methyl-3-oxo-3, 5-dihydro-2H-thiazolo [3, 2-a] pyrimidine-6-carboxylate derivatives
Dihydropyrimidinone derivatives were prepared by tri-component reaction of ethyl aceto acetate, aldehydes and thiourea in the presence of modified montmorillonite nanostructure as a catalyst and used as key intermediates for the synthesis of ethyl-5-(aryl)-2-(2-alkokxy-2-oxoethylidene)-7-methyl-3-oxo-3,5-dihydro-2H-thiazolo[3,2-a]pyri midine-6-carboxylate derivatives with use of diethyl and dimethyl acetylene dicarboxylate by two methods: (a) in methanol as a solvent under ultrasonic irradiation at ambient temperature (b) in methanol as a solvent at ambient temperature (conventional magnetic stirring). Ultrasound-assisted synthesis provides excellent yields in short reaction times (15-25 min) at room temperature. (C) 2015 The Authors. Published by Elsevier B.V. on behalf of King Saud University.
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 6192-52-5. Formula: C7H10O4S.
