(S)-Methyl 4-methyl-2-(1H-pyrrole-2-carboxamido)pentanoate

X.-C. Zeng and P.-R. Liu

Abstract: The title compound, C₁₂H₁₈N₂O₃, was synthesized in 87.2% yield by condensation of L-leucine methyl ester with 2-trichloroacetylpyrrole at room temperature. There are two chemically equivalent and crystallographically independent molecules in the asymmetric unit. In the crystal structure, intermolecular N-HO hydrogen-bonding interactions link the molecules into extended chains parallel to the c axis.
