The present invention relates to N-benzyl,N' -arylcarbonylpiperazine derivatives having the general Formula (I) to pharmaceutical compositions comprising the same, and to the use of a these N-benzyl,N' -arylcarbonylpiperazine derivatives for the manufacture of a medicament for treating or preventing atherosclerosis and related disorders associated with cholesterol and bile acids transport and metabolism.
Two stereocontrolled routes to the tricyclic core of (-)-callophycoic acid A are described. Our synthetic strategy relied on stereoselective allylboration using a new allylboronate reagent to construct the all-carbon quaternary stereocenter in the core, followed by efficient radicalcyclization or palladium-catalyzed reductive cyclization to form its multisubstituted cyclohexane ring. The tetrahydrooxepin

Highly regioselective ruthenium-catalyzed direct benzylations through C-H bond cleavages were accomplished under remarkably mild, nonacidic reaction conditions, for which experimental studies suggested a SEAr-type mechanism not to be operative.
