An efficient synthesis of coniochaetone A and of racemate coniochaetone B was achieved by a short five-step procedure from methyl di-O-methyl-p-orsellinate. The key step is a cascade reaction of 2′-hydroxy-6′-methoxy-4′-methyl-2-(methylsulfinyl)- acetophenone with succindialdehyde in the presence of piperidine which allows the direct building of the tricyclic benzopyranone structure.
