bi- and tricyclic aryl methyl ketones in one single working process. Crucial steps are the addition of 1-ethoxyvinyllithium to the carbonyl group, followed by acid-catalyzed enol ether hydrolysis, dehydration, and dehydrogenation. This work describes a straightforward multistep conversion of substrates containing a cyclohexenone moiety into mono-, bi- and tricyclic aryl methyl ketones in one single working

transformation reactions with guanidine. Only after N‐protection (methyl or 2‐(trimethylsilyl)ethoxymethyl group), 2‐desazaanalogues of the alkaloidannomontine are accessible via the enaminoketones obtained by condensation with Bredereck's reagent. One of the annomontineanalogues is an inhibitor of the Plasmodium falciparum CDC‐like kinases (CLK) and shows antimalarial activity.
