Tert-Butyl 2-(dihydroxyboryl)pyrrole-1-carboxylate.

ABSTRACT: In the title compound, C(9)H(14)BNO(4), the carbonyl and boronic acid groups are essentially coplanar with the pyrrole ring and the boronic acid group has an exo-endo conformation. The exo-oriented OH is engaged in an intra-molecular O-H?O inter-action, while the endo-oriented one is involved in inter-molecular hydrogen bonding to form centrosymmetric dimers. A supra-molecular assembly is achieved through inter-actions involving the tert-butyl groups, forming infinite chains along the crystallographic b axis. There are, in addition, face-to-face and center-to-edge stacking inter-actions [distance between the pyrrole ring centroid and an N atom from a neighbouring mol-ecule = 3.369?(8)?Å].
