Gonytolide A (1), a dimeric chromanone substituted with the-lactone, shows promoting activity of innate immune responses. However, biological studies on this compound have been limited by the low amounts of 1 available from natural resources and the difficulty of its synthesis. In this study, we designed and synthesized structure-simplified gonytolide derivatives. Bischromone 10 and biflavone 13 both promoted the mammalian TNF-α signaling pathway and Drosophila innate immunity. They did not contain a chiral center and were easy to synthesize. Hence, they can be used as lead compounds for a new type of immunostimulating drugs and as research reagents.
The first synthesis of coniochaetones A and (±)-B: Two benzopyranone derivatives

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.
