Tetra­methyl 1,4-dimethyl-13,14-dioxa­penta­cyclo­[8.2.1.1(4,7).0(2,9).0(3,8)]tetra­deca-5,11-diene-5,6,11,12-tetra­carboxyl­ate

In the title compound, C(22)H(24)O(14), the relative stereochemistry at the cyclo­butane ring is cis-anti-cis and the methyl groups in the bicyclic rings are syn to each other. The two carboxyl­ate groups attached to the same —C=C— bond are disordered over two sets of sites in a 0.603 (2):0.397 (2)...

Descripción
Sumario:In the title compound, C(22)H(24)O(14), the relative stereochemistry at the cyclo­butane ring is cis-anti-cis and the methyl groups in the bicyclic rings are syn to each other. The two carboxyl­ate groups attached to the same —C=C— bond are disordered over two sets of sites in a 0.603 (2):0.397 (2) ratio. In the crystal, weak C—H⋯O hydrogen bonds connect mol­ecules into C(12) chains along [001] incorporating R (2) (2) (2)(10) rings.
