Abstract: The regio- and absolute stereochemistry of the title compound, ethyl 3,6-diacetoxy-11-[1-(4- nitrobenzoyloxy)ethyl]tetracyclo[6.4.1.0^2,7.0^9,12]trideca-2,4,6,10-tetraene-10-carboxylate, C₂₉H₂₇O₁₀, has been established. In the crystal structure, weak intermolecular hydrogen bonds link molecules into a three-dimensional network.
