Abstract :
Oxidation of dihydroquinopimaric acid methyl ester and its derivatives with dimethyldioxirane results in the formation of a nontrivial derivative and hemiacetals in high yields with excellent regioselectivity, as is demonstrated for an unsaturated diol. The structures of the products were confirmed by X-ray crystallographic analysis. Dihydroquinopimaric acid and its nontrivial derivative are found to be moderately active against influenza virus type A and the papilloma virus.
