Methyl 2 , 5 - Dihydroxy - 4 - ( 3 1 - methyl - 2 1 - butenyl ) benzoate
Methyl 2,5-dihydroxy-4-(31-methyl-21-butenyl)benzoate (1) was isolated from the root of Erythrina subumbrans. The chemical structure of 1 has been elucidated based on spectroscopy UV-Vis, HRESIMS, 1D and 2D NMR analysis.
متن کاملSynthesis, Reactions and Antioxidant Activity of 5-(3', 4'-dihydroxy-tetrahydrofuran-2'-yl)-2-methyl-3-carbohydrazide
In this manuscript, we describe the synthesis of the carbohydrazide 2. Acid-catalyzed condensation with several carbonyl compounds to afford the corresponding carbohydrazide derivatives 3-12. Their acetylation afforded the corresponding acetyl derivatives 13-22. Oxidative cyclization of O-acetyl derivatives 19-22 afforded the corresponding 1,3,4-oxadiazole derivatives 23-2...
متن کامل2, 4-Dihydroxy-5-Bromo [2’Methyl] Propiophenone Thiosemicarbazone [DHBMPT] as an Analytical Reagent: Studies on Pd (II) Chelate
2, 4-Dihydroxy-5-Bromo-[2’methyl]-Propiophenone thiosemicarbazone [DHBMPT] has been used for the spectrophotometric determination of Pd(II) at pH = 2.5. Job’s method of continuous variation and Yoe and Jones Mole ratio method show metal: ligand ratio in the complex to be 1:1. The molar absorptivity of complex at 390 nm was found to be 1.457 x10 lit.mol.cm and Sandell’s sensitivity was found to ...
متن کامل2-Methyl-5-nitrobenzenesulfonamide
In the title compound, C(7)H(8)N(2)O(4)S, the nitro group is twisted by 9.61 (2)° relative to the benzene ring. In the crystal, mol-ecules are linked by N-H⋯O and N-H⋯(O,O) hydrogen bonds between the amino and sulfonyl groups, forming layers parallel to (001).
متن کامل2-Methyl-5-nitrobenzonitrile
In the title compound, C(8)H(6)N(2)O(2), the nitro group is rotated by 10.2 (2)° out of the plane of the benzene ring. The crystal structure is stabilized by van der Waals inter-actions.
