An unprecedented C-3-alkenylation of quinolones was reported through palladium-catalyzed CH functionalization with 1% catalyst loading. This method provides an efficient route to a variety of new quinolone derivatives.

The titanium(III)-catalysed cross-selective reductive umpolung of Michael-acceptors represents a unique direct conjugate β-alkylation reaction. It allows the cross-selective preparation of 1,6- and 1,4-difunctionalised building blocks without the requirement of stoichiometric organometallic reagents. In this full paper, the development and scope of the titanium(III)-catalysed cross-selective reductive
