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 کاملCorrelation between urinary 2-methoxy acetic acid and exposure of 2-methoxy ethanol.
OBJECTIVES To examine the correlation between airborne 2-methoxy ethanol (ME) exposures and the urinary 2-methoxy acetic acid (MAA) and to recommend a biological exposure index (BEI) for ME. METHODS 8 Hour time weighted average (TWA) personal breathing zone samples and urine samples before and after the shift were collected from Monday to Saturday for 27 workers exposed to ME and on Friday fo...

متن کاملThermodynamics of binding of 2-methoxy-3-isopropylpyrazine and 2-methoxy-3-isobutylpyrazine to the major urinary protein.
In the present study we examine the thermodynamics of binding of two related pyrazine-derived ligands to the major urinary protein, MUP-I, using a combination of isothermal titration calorimetry (ITC), X-ray crystallography, and NMR backbone (15)N and methyl side-chain (2)H relaxation measurements. Global thermodynamics data derived from ITC indicate that binding is driven by favorable enthalpi...
متن کاملtert-Butyl 2-[4-(2-{4-[(tert-butoxycarbonyl)methoxy]-3-methylphenyl}-2-propyl)-2-methylphenoxy]acetate
In the mol-ecule of the title compound, C(29)H(40)O(6), the carbon atom belonging to the propyl chain is connected to two aromatic rings that open up the C(ar-yl)-C-C(ar-yl) angle to 111.5 (1)°. The four-atom -O-CH(2)-C(=O)-O- linkage between the aromatic ring and the tert-butyl group assumes a (-)anti-periplanar conformation for one substituent and a (-)syn-periplanar conformation for the othe...
