Synthetic Route of 531-91-9, New discoveries in chemical research and development in 2021.Chemistry can be defined as the study of matter and the changes it undergoes. 531-91-9, Name is N4,N4′-Diphenyl-[1,1′-biphenyl]-4,4′-diamine, SMILES is C1(C2=CC=C(NC3=CC=CC=C3)C=C2)=CC=C(NC4=CC=CC=C4)C=C1, belongs to thiomorpholine compound. In a article, author is REDDY, DB, introduce new discover of the category.
A series of new 2-aroyl-3, 5-diaryltetrahydro-1, 4- thiazine-1, 1-dioxides (2) has been synthesized either from phenacylsulfonylacetic acids (1) or phenacylstyryl sulfones (3), which in turn are obtained from the substituted acetophenones or styrenes, respectively. Another series of alkoxycarbonyl-3-aryl-5(4-methyl-phenyl)tetrahydro-l, 4-thiazine-1, 1-dioxides (5) has been prepared from Z (or E)-alkyl 4-methylstyrylsulfonyl acetates (4). The desired 4 has been obtained from the corresponding acetylenes or 4-methylstyrene. The structures of 2 and 5 and their preferred chair conformations have been deduced by the analysis of high resolution NMR data supported by correlation spectroscopy.
