Multiple Regioselective Functionalizations of Quinolines via Magnesiations
摘要:
A wide range of polyfunctionalized quinolines was prepared via chemo- and regioselective magnesiation reactions using appropriate Mg reagents, such as i-PrMgCl center dot LiCl, MesMgBr center dot LiCl, Mes(2)Mg center dot 2LiBr, TMPMgCl-LiCl, and TMP2Mg center dot 2LiCl. An application to the total synthesis of the biologically active compound talnetant was performed (six steps, 28%).

In a series of studies, the regioselectivity of Suzuki couplings of dibromoquinolines has been investigated. In general, it is much harder to achieve high levels of regioselectivity in these systems compared to many of the other dibromoheteroaromatics that have been studied. Useful levels of selectivity could be achieved for both a 5,7-dibromoquinoline as well as 3,4-dibromoquinoline. Double Suzuki couplings could also be achieved on these two compounds.
