Base-Mediated O-Arylation of Alcohols and Phenols by Triarylsulfonium Triflates

A mild and efficient protocol for O-arylation of alcohols and phenols (ROH) by triarylsulfonium triflates was developed under transition-metal-free conditions. Various alcohols, including primary, secondary and tertiary, and phenols bearing either electron-donating or electron-withdrawing groups on the aryl rings were smoothly converted to form the corresponding aromatic ethers in moderate to excellent yields. The reactions were conducted at 50 or 80 °C for 24 h in the presence of a certain base and showed good functional group tolerance. The base-mediated arylation with asymmetric triarylsulfonium salts could selectively transfer the aryl groups of sulfoniums to ROH, depending on their inherent electronic nature. The mechanistic studies revealed that the reaction might proceed through the nucleophilic attack of the in situ formed alkoxy or phenoxy anions at the aromatic carbon atoms of the C?S bonds of triarylsulfonium cations to furnish the target products.

Naphthyloxy acetic acid derivatives and a pharmaceutical composition comprising them as an active ingredient

The naphthyloxyacetic acid derivatives of the formula (I) wherein A is H, -(alkylene)COOR1, -(alkylene)CONR2R3, -(alkylene)OH, -(alkylene)tetrazole, -(alkylene)CN; E is single bond or alkylene; G is —S—, —SO—, —SO2—, —O— or —NR4—; L is alkylene, —(CH2)m—CH═CH—(CH2)n— or —(CH2)x—CH(OH)—(CH2)y—; M is phenyl, phenyl(thio, oxy, amino), diphenylmethyl, diphenylmethyl(thio, oxy, amino), and pharmaceutical composition comprising them as an active ingradient. The compounds of the formula (I) can combine PGE2receptor and exhibit the activity to antagonize or agonize for PGE2receptor. Therefore, they are useful as anti-hyperlipemia, for the prevention of abortion, for analgesics, as antidiarrheals, sleep inducer, diuretic, anti-diabetes, abortient, cathartics, antiulcer, anti-gastritis or antihypertensive etc.

Relationships between conformational behaviour and binding affinity towards β1 and β2 adrenoceptors of some chiral phenoxypropanolamines with bulky N-substituents

The optical isomers of a series of phenoxypropanolamine compounds with N-substituents bulkier than isopropyl have been synthesized, and their binding affinity towards β1 and β2-adrenoceptors has been determined. A computational study, including a Molecular Dynamics (MD) simulation and quenching in water and a GRID analysis provided some useful suggestions for possible interpretation patterns for the different affinity exhibited by the compounds studied.
