Chemical engineers ensure the efficiency and safety of chemical processes, adapt the chemical make-up of products to meet environmental or economic needs, and apply new technologies to improve existing processes. 58446-52-9, Name is 1-Phenylicosane-1,3-dione, molecular formula is C26H42O2, belongs to isothiazole compound. In a document, author is CLERICI, F, introduce the new discover, Name: 1-Phenylicosane-1,3-dione.
N-alkylsulfonylamidines of alpha-ketoacids 3 bearing both a carbonyl group and at least one H-atom near to the SO2 group give easily an intramolecular ring-closure reaction by action of potassium t-butoxide producing the 3-amino-4,5-dihydro-4-hydroxy-isothiazole S,S-dioxides 4. Compounds 4 are transformed by thionyl chloride into the corresponding chloro-derivatives 5 which in turn are dehydrochlorinated by potassium carbonate to substituted 3-amino-isothiazole S,S-dioxides 6.
The result showed that such a combination of chemo- and biocatalysis improved the catalytic yield more than two times compared with that of sole metal catalysis.I hope my blog about 58446-52-9 is helpful to your research. Name: 1-Phenylicosane-1,3-dione.
