摘要:Abstract(#br)Heck reactions of perfluoroalkyl vinyl sulfoxides with aryl iodides are studied and palladium(II) acetate is shown to be the most convenient catalyst for this process. New E -1-aryl-2-perfluoroalkylsulfinylethylenes are synthesized. In all cases, by-products without ...

摘要:Abstract(#br)Ethyl 3-aryl and 3-alkyl-2-(trifluoromethylthio)acrylates as well as 2-(trifluoromethylthio)acrylate ( 3 ) are readily prepared by the Knoevenagel condensation of ethyl (trifluoromethylthio)acetate ( 2 ) with aldehydes under mild conditions.

摘要:Abstract(#br)Direct perfluoroalkylation of aliphatic thiols was performed in the presence of sodium hydroxymethanesulfinate (Rongalite). Reaction of mercaptoalkanoic esters with trifluoromethyl bromide gave the corresponding trifluoromethylthio ethers. Condensation of alkane dith...

摘要:Abstract(#br)The expression of the tachykinin NK 3 receptor and its regulation by ovarian steroids were analyzed by reverse transcription-polymerase chain reaction (RT-PCR) in uteri from ovariectomized rats. A single transcript corresponding to the 325-bp product expected for the...

摘要:Abstract(#br)The absence of reactivity of imines towards Ruppert's reagent (CF 3 SiMe 3 ) could be overcome by the addition of an auxiliary silylating agent to the reaction medium. Under these conditions variously substituted α-trifluoromethylated amines are readily obtained...

摘要:Abstract(#br)We investigated the effect of Mn 2+ on the mechanical responses evoked by high K + (60 mM) or low Na + (25 mM) solutions, oxytocin and neurokinin A in the oestrogen-primed rat uterus. In a Ca 2+ -free, Mn 2+ (0.54 mM)-containing solution, high K + or low Na + so...

摘要:Abstract(#br)The synthesis of 2-trifluoromethoxyethyl trifluoromethoxyacetate 2 by oxidation of bis(2-trifluoromethoxyethyl)ether 1 followed by its anionic condensation with aldehydes, ketones and immonium salts under mild conditions, and further dehydration or deamination, ...

摘要:Abstract(#br)In the present study we examine the mechanism by which thaligrisine, a bisbenzyltetrahydroisoquinoline alkaloid, inhibits the contractile response of vascular smooth muscle. The work includes functional studies on rat isolated aorta and tail artery precontracted...
