✦ Synopsis

In the title molecule, C 22 H 22 N 2 O 6 , the planes of the two methoxycarbonyl groups are oriented at angles of 5.19 (14) and 80.21 (9) with respect to that of the indolizine ring. In the crystal structure, the molecules are linked by weak intermolecular C-HÁ Á ÁO interactions to form centrosymmetric ring motifs.
