چکیده
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].

An efficient enantioselective synthetic method for the synthesis of (2R)-5-phenyl-2-alkylproline tert-butyl esters was reported. The phase-transfer catalytic alkylation of tert-butyl-5-phenyl-3,4-dihydro-2H-pyrrole-2-carboxylate in the presence of chiral quaternary ammonium catalysts gave the corresponding alkylated products (up to 97% ee). The following diastereoselective reductions afforded c...
