Diethyl indolizine-1,3-dicarboxylate

Abstract

The title compound, C14H15NO4, was prepared by a 1,3-dipolar cycloaddition from N-(ethoxycarbonylmethy)-pyridinium bromide and ethyl acrylate. The -CO2 side chains form dihedral angles of 0.2 (3) and 2.4 (3)° with respect to the ring system. In the crystal, two neighbouring molecules form a dimer through weak C - H⋯O interactions. The dimers form a three-dimensional structure via further weak C - H⋯O interactions.
