New rifabutin analogs: Synthesis and biological activity against Mycobacterium tuberculosis
摘要:
The synthesis, structure, and biological evaluation of a series of novel rifamycin derivatives, Rifastures (RFA) with potent anti-tuberculosis activity are presented. Some of these derivatives showed higher in vitro activity than rifabutin and rifampicin against not only Mycobacterium tuberculosis strains but also against MAC and Mycobacterium kansasii.

A convenient stereoselective preparation of meso- and cis-2,6-diarylpiperidin-4-ones has been developed by aza-Diels-Alder reaction catalyzed by l-proline from simple and commercially available starting materials.
Amine-catalyzed imino-Diels–Alderreactions of acyclic α,β-unsaturated ketones with imines have been developed. L-Proline catalyzed the in situ generation of 2-amino-1,3-butadienes to provide a stereoselective synthesis of meso-2,6-diaryl-4-piperidones in one direct step.
