چکیده
The title compound, C(9)H(11)NO(3), was prepared by an Aldol reaction of 2,3-dihydro-1H-pyrrolizin-1-one with formaldehyde. The asymmetric unit contains six mol-ecules. The pyrrolizine ring system in each mol-ecule is planar, the maximum atomic deviation being 0.066 (2) Å. In the crystal structure, mol-ecules are liked together by an extensive O-H⋯O hydrogen-bonding network.

The title compound, C(12)H(9)NO(2), was prepared by an Aldol reaction of furfuraldehyde with 2,3-dihydro-1H-pyrrolizin-1-one. The mol-ecule is almost planar, with an r.m.s. deviation of 0.045 Å, excluding the methyl-ene H atoms. In the crystal structure, mol-ecules are linked via weak inter-molecular C-H⋯O hydrogen bonding and aromatic π-π stacking [centroid-centroid distance = 3.6151 (9) Å].

2-[6-(4-Chlorophenyl)-2,2-dimethyl-7-phenyl-2,3-dihydro-1H-pyrrolizin-5-yl] acetic acid (licofelone) is a dual inhibitor of both cyclooxygenase isoforms and 5-lipoxygenase and under development for treatment of osteoarthritis. In conventional in vitro assays using liver microsomes and NADPH as cosubstrate, a high metabolic stability of licofelone was observed. In the presence of UDP-glucuronic ...
