Abstract: In the crystal structure of the title compound, C₉H₁₄BNO₄, the boronic acid group and carbamate groups are nearly co-planar with the pyrrole ring, making dihedral angles of 0.1 (2) and 2.2 (2)°, respectively. Intramolecular and intermolecular O-HO hydrogen bonds help to stabilize the structure, the latter interaction leading to inversion dimers..
