radioactivity of 84 GBq/mmol from 10 GBq of [11C]carbonmonoxide. [1-11C]Propyl iodide was synthesized with a specific radioactivity of 270 GBq/mmol from 12 GBq and [1-11C]butyl iodide with 146 GBq/mmol from 8 GBq.Palladium-mediated hydroxycarbonylation of acetylene was used in the synthesis of [1-11C]acrylic acid. The labelled carboxylic acid was converted to its acid chloride and subsequently treated with

addition, we note a correlation between 1H and 13C NMR chemicalshifts of the acrylamide with GSH reaction rates, suggesting that NMR chemicalshifts may be a convenient surrogate measure of relative acrylamide reactivity. Density functional theory calculations reveal a correlation between computed activation parameters and experimentally determined reaction rates, validating the use of such methodology
The Morita-Baylis-Hillman reaction of acrylamide, as an activated alkene, has seen little development due to its low reactivity. We have developed the reaction using isatin derivatives with acrylamide, DABCO as a promoter and phenol as an additive in acetonitrile. The corresponding aza version with acrylate and acrylonitrile has also been developed resulting in high product yields.
1,3-Butadiene plays a key role in modern synthetic chemistry and biochemistry because it is a key intermediate in the synthesis of many drugs. A new and effective method for the synthesis of 4-trifluoromethylated 1,3-butadiene through the fluorinated Heckreaction catalyzed by Pd(0) is described. Without additives, 1-chloro-3,3,3-trifluoropropene (an inexpensive CF3 structural unit that is harmless

phorylnitrone and N-arylacrylamides in good yields. cis- and trans-isoxazolidine phosphonates obtained herein were evaluated for activity against a broad range of DNA and RNA viruses. None of the compounds were endowed with antiviral activity at subtoxic concentrations. Isoxazolidines having phenyl substituted with halogen (Ar = 2-F-C6H4; 3-Br-C6H4; and 4-Br-C6H4) have been found to inhibit proliferation
