title: tert-Butyl 3-[2,2-bis-(ethoxy-carbon-yl)-vinyl]-2-methyl-1H-indole-1-carboxyl-ate.
abstract: In the title compound, C(22)H(27)NO(6), the indole ring system is planar and the ethoxy-carbonyl chains adopt extended conformations. In the crystal, inversion dimers linked by pairs of C-H⋯O hydrogen bonds occur, resulting in R(2) (2)(16) dimers, which are inter-linked into a chain propagating along the a axis by π-π stacking inter-actions [centroid-centroid distance 3.5916 (9) Å].
