You¡¯ll sometimes hear it called the central science because it is the connection between physics and all the other sciences, starting with biology.Product Details of 18331-34-5, Name is 5-Benzylidene-3-ethyl-2-thioxothiazolidin-4-one, molecular formula is C12H11NOS2, introducing its new discovery.
Introduction of Selenium to Heterocyclic Compounds. Part VII. Synthesis of 3-Alkyl-5-benzylidene- and 3-Alkyl-5-cinnamylidene-2-selenorhodanines
Five new 3-alkyl-5-benzylidene- and five new 3-alkyl-5-cinnamylidene-2-selenorhodanines were obtained by treatment of methylation products of appropriate rhodanines with H2Se. The stability of 2-thiazolinium salts with SCH3 or RNHCH3 group formed during methylation (cf. Scheme 2) is determined by substituents at C-5 and N-3 atoms.
