The present invention provides compounds of Formula (I) or Formula (III): [INSERT CHEMICAL STRUCTURE HERE] (I) [INSERT CHEMICAL STRUCTURE HERE] (III) as defined in the specification and compositions comprising any of such novel compounds. These compounds are endothelial lipase inhibitors which may be used as medicaments.
Radicals produced via the indirect reduction of alkyl halides by aromatic radical anions are likely to couple fast with the mediator. In the presence of activated olefins or good hydrogen atom donors the fate of the alkyl radicals might be changed. In this study rate constants for the coupling reaction (2) between primary, secondary and tertiary alkyl radicals and some aromatic radical anions were measured via the competition with addition of the radical to styrene or ethyl cinnamate, or via the competition with hydrogen atom transfer from thiophenol or 2-methyl-2-propanethiol to the alkyl radical. It is shown that for all the alkyl radicals and aromatic radical anions investigated so far the rate constant for coupling is close to 1 x 10(9) M-1 s(-1).
