2-Ethyl 4-methyl 5-ethyl-3-methyl-1H-pyrrole-2,4-dicarboxyl­ate

The title pyrrole derivative compound, C(12)H(17)NO(4), was synthesized from methyl 3-oxopenta­noate by a Knorr-type reaction and contains a pyrrole ring to which two diagonal alk­oxy­carbonyl groups and two diagonal alkyl substituents are attached. The methyl­carbonyl and ethyl­carbonyl substituent...

description The title pyrrole derivative compound, C(12)H(17)NO(4), was synthesized from methyl 3-oxopenta­noate by a Knorr-type reaction and contains a pyrrole ring to which two diagonal alk­oxy­carbonyl groups and two diagonal alkyl substituents are attached. The methyl­carbonyl and ethyl­carbonyl substituents are approximately co-planar with the pyrrole ring, making dihedral angles of 5.64 (2) and 3.44 (1)°, respectively. In the crystal, adjacent mol­ecules are assembled by pairs of N—H⋯O hydrogen bonds into dimers in a head-to-head mode.
