Diethyl 7,8,18,19-tetra-methyl-2,13-dioxo-hexa-cyclo-[10.10.2.0.0.0.0]tetra-cosa-5,7,9,16,18,20-hexa-ene-23,24-dicarboxyl-ate.

ABSTRACT: The asymmetric unit of the title compound, C(30)H(34)N(4)O(6), contains two independent mol-ecules. In one independent mol-ecule, the two eth-oxy-carbonyl groups are each disordered over two conformations with occupancy ratios of 0.586 (2):0.414 (2) and 0.508 (2):0.492 (2). The crystal packing exhibits weak inter-molecular C-H⋯O hydrogen bonds.
