L.-H. Li, X.-C. Zeng and P.-R. Liu

Abstract: The title compound, C₁₂H₁₆Br₂N₂O₃, synthesized by the condensation of L-leucine methyl ester with 4,5-dibromo-2-trichloroacetylpyrrole at room temperature, crystallizes with two independent molecules in the asymmetric unit. Intermolecular N-HO hydrogen bonds link the molecules into ribbons extending along the b axis.
