A catalyst don’t appear in the overall stoichiometry of the reaction it catalyzes, Safety of Sodium 3-nitrobenzoate, but it must appear in at least one of the elementary reactions in the mechanism for the catalyzed reaction. 827-95-2, Name is Sodium 3-nitrobenzoate, molecular formula is C7H4NNaO4. In an article, author is Benharref, Ahmed,once mentioned of 827-95-2.
Crystal structure of (1S,2R,4R,9S,11S,12R)-9 alpha-hydroxy-4,8-dimethyl-12-[(thiomorpholin-4-yl)methyl]-3,14-dioxatricyclo[9.3.0.0(2,4)]tetradec-7-en-13-one
The title compound, C19H29NO4S, was synthesised from 9 alpha-hydroxyparthenolide (9 alpha-hydroxy-4,8-dimethyl-12-methylene-3,14-dioxatricyclo[9.3.0.0(2,4)]tetradec-7-en-13-one), which was isolated from the chloroform extract of the aerial parts of the plant Anvillea radiata. The molecule is built up from two fused five-and ten-membered rings, with an additional epoxy ring system and a thiomorpholine group as a substituent. The ten-membered ring adopts an approximate chair-chair conformation, while the thiomorpholine ring displays a chair conformation and the five-membered ring has an envelope conformation, with the C atom closest to the hydroxy group forming the flap. An intramolecular O-H center dot center dot center dot N hydrogen bond closes an S(8) ring. The crystal structure features weak C-H center dot center dot center dot O hydrogen-bonding interactions, which link the molecules into [010] chains.
