aldol condensation from various ketones and a wide range of aldehydes was catalyzed by l-proline–TEA (triethylamine) in MeOH at room temperature, affording the corresponding (E)-α,β-unsaturated ketones in excellent yields. By using the method, some complicated (E)-α,β-unsaturated ketone C-glycosides were obtained from unmodified ketone C-glycosides and aldehydes. This reaction proceeds through a new

anones can be realized through cross aldol-type reaction of the ketones and aromatic aldehydes, but traditional acidor base-catalyzed reaction suffers from reverse reaction and thus gives the corresponding products in low yields.2 Aoyama and coworkers' obtained a,d-bis(benzy1idene)cyclohexanones through Rh(II1)-porphyrin complexcatalyzed condensation in only 30% yields, while Nakano and co-workers4

monoketone derivatives of curcumin were synthesized to investigate the synergy with fluconazole against fluconazole-resistant Candida spp. The minimal inhibitory concentration (MIC80) and the fractional inhibitory concentration index (FICI) of the antifungal synergist fluconazole were measured against fluconazole-resistant C. albicans, C. tropicalis and C. krusei in vitro. Most of these compounds showed
