In this paper, a new cycloaddition between α,β-unsaturated aldehydes and coumalates realized under dienamine activation has been described. The reaction proceeds regioselectively with the distal double bond of the dienamine system acting as electron-rich dienophile. It leads to the formation of biologically relevant [2.2.2]-bicyclic lactones. Their functionalization potential has been confirmed in
The first iridium-catalyzed enantioselective olefinic C(sp2)–H allylicalkylation is developed in cooperation with Lewisbasecatalysis. This reaction, catalyzed by cinchonidine and an in situ generated cyclometalated Ir(I)/phosphoramidite complex, makes use of the latent enolate character of an α,β-unsaturated carbonyl compound, namely coumalate ester, to introduce an allyl group at its α-position
