Tetra-methyl 1,4-dimethyl-13,14-dioxa-penta-cyclo-[8.2.1.1(4,7).0(2,9).0(3,8)]tetra-deca-5,11-diene-5,6,11,12-tetra-carboxyl-ate.

ABSTRACT: In the title compound, C(22)H(24)O(14), the relative stereochemistry at the cyclo-butane ring is cis-anti-cis and the methyl groups in the bicyclic rings are syn to each other. The two carboxyl-ate 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 mol-ecules into C(12) chains along [001] incorporating R(2) (2) (2)(10) rings.

3,8-Bis(4-chloro-phen-yl)-4,7-dimethyl-tricyclo-[4.2.2.0]deca-3,7-diene.

Project description:The title tricyclic diene, C(24)H(22)Cl(2), is the product of thermal ring-opening of a corresponding basketane (penta-cyclo-[4.4.0.0(2,5).0(3,8).0(4,7)]deca-ne) derivative.

The two 4-chloro-phenyl groups are oriented in an approximately face-to-face conformation with a dihedral angle of 44.14?(6)° between them. The 4-chloro-phenyl group bonded to the cyclo-butene ring lies almost in the plane of the cyclo-butene ring, with a dihedral angle of 8.29?(17)° between the ring planes. The average intra-molecular C?C distance between the two C=C bonds is 2.92?Å. In the crystal structure, the mol-ecules are well separated with no close C-H?Cl or C-H?? inter-molecular inter-actions.
