3-Methoxy-4-(4-nitrobenzyloxy)benzaldehyde
In the title compound, C(15)H(13)NO(5), the vanillin group makes a dihedral angle of 4.95 (8)° with the benzene ring of the nitro-benzene group. The packing is stabilized by weak, non-classical inter-molecular C-H⋯O inter-actions which link mol-ecules into chains running along the c axis.
متن کاملSYNTHESIS OF 8-HYDROXY-6-METHOXY- 3-UNDECYLISOCOUMARIN AND 2-HY DROXY - 4-METHOXY-6-(2-OXOTRIDECYL) BENZOIC ACID
Straightforward conversion of (+)-6,8-dimethoxy-3,4-dihydro-3- undecylisocoumarin (3) to the title isocoumarin was carried out. Hydrolytic ring opening of (3) afforded the hydroxy acid (4) which was immediately oxidized to keto acid (5) using chromic acid, Cyclodehydration of (5) afforded the 6,8- dimethoxy-3-undecylisocoumarin (6) which on selective demethylation of 8- methoxy group furni...
متن کاملSynthesis and anti-tubercular activity of 6-Substtitutedaryl-4-Arylidene-4,5-dihydropyridazin-3(2H)-one derivatives against Mycobacterium tuberculosis
Pyridazine plays a significant role in pharmaceuticals particularly in the field of medicinal chemistry. Several 4-substituted-benzylidene-6-substituted-phenyl-dihydro-pyridazin-3(2H)-one derivatives (3a-q) were synthesized and evaluated for their antimicrobial activities with an aim to obtain promising antitubercular agents. In the first step, 6-aryl-tetrahydro-pyridazin-3-ones (2) were prepar...

متن کاملEvaluation of plasma 3-methoxy-4-hydroxyphenylglycol.
A high-performance liquid chromatographic (HPLC) assay suitable for the evaluation of 3-methoxy-4-hydroxyphenylglycol (MHPG) in 1-ml aliquots of plasma is presented. Preparatory steps include extraction into ethyl acetate and minicolumn chromatography. Recoveries are monitored with [3H]MHPG. The HPLC procedure utilizes a C18 column, isocratic elution and amperometric detection. The assay was ch...
