Abstract
The asymmetric unit of the title compound, C(26)H(36)N(2)O(8), comprises two independent mol-ecules. In each mol-ecule, the two pyrrole rings are linked by a -CH(2)CH(2)- bridge, with dihedral angles between the two pyrrole rings of 14.5 (3) and 16.4 (3)° in the two mol-ecules. Each pyrrole ring carries 2- and 5-methyl substituents and eth-oxy-carbonyl groups at the 3- and 5-positions.
摘要
标题化合物C(26)H(36)N(2)O(8)的不对称单元包含两个独立分子。在每个分子中，两个吡咯环通过一个-CH(2)CH(2)-桥相连，两个分子中两个吡咯环之间的二面角分别为14.5 (3)°和16.4 (3)°。每个吡咯环在3-和5-位带有2-和5-甲基取代基以及乙氧羰基。
