The firstchemicalsynthesis of S2502 and S2507, highly active antiviral, bioengineered fermentation products, has been achieved using a biomimetic approach. Key steps of the synthesis involved addition of the dianion of acetylacetone to isochromene 10, followed by boron tribromide mediated simultaneous methyl ether cleavage, E/ Z isomerization, cyclization, and transesterification/saponification to
