SYNTHESIS 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 کاملBis(2-iodothiophen-3-yl)methanone
In the title mol-ecule, C(9)H(4)I(2)OS(2), the two five-membered rings form a dihedral angle of 64.2 (2)°. In the crystal, weak inter-molecular C-H⋯O hydrogen bonds link the mol-ecules into layers parallel to the ab plane. The crystal packing exhibits short C⋯I contacts of 3.442 (5) Å between the mol-ecules of adjacent layers.
متن کاملNeuroprotection of a sesamin derivative, 1, 2-bis [(3-methoxy- phenyl) methyl] ethane-1, 2-dicaroxylic acid (MMEDA) against ischemic and hypoxic neuronal injury
Objective(s): Stroke may cause severe neuronal damage. The sesamin have been demonstrated to possess neuroprotection by its antioxidant and anti-inflammatory properties. One sesamin derivative was artificially composited, 1, 2-bis [(3-methoxyphenyl) methyl] ethane-1, 2-dicaroxylic acid (MMEDA) had been developed to study its antioxidative activity and neuroprotection. Materials and Methods: The...
متن کاملSynthesis and evaluation of antirhinovirus activity of 3-hydroxy and 3-methoxy 2-styrylchromones.
Recently, we identified 2-styrylchromones as a new class of antirhinovirus flavonoids with moderate activity against both rhinovirus groups A and B. In order to improve the antiviral effect of the first series of tested 2-styrylchromones, a hydroxy or methoxy group was introduced in position 3 of the chromone ring. Cytotoxicity and antiviral activity of the new synthesized compounds were evalua...
