Disclosed is a chalcone composition for treating diabetes and metabolic syndromes. In particular, the chalcone compound bound with 2-halogen in ring A significantly decreases the blood glucose level in the in vitro anti-diabetic effect experiment. In the in vivo animal model, the leading chalcone compound can prevent the progression of diabetes and control the blood glucose level, and there is no significant difference in the gains in body weight. Throughout the seven-week administration, there are no hepatic or renal toxicity observed.
process for the formation of diethyl 2-aryl-3,4-dihydro-4-oxo-1,1(2H)-naphthalenedicarboxylate is described by using a combination of Michael addition and copper-catalyzed α-arylation of malonicacidderivatives. The protocol worked well for a variety of 1-(2-iodoaryl)enones and displayed great functional group compatibility. Michael addition - copper - catalysis - cascade reactions- α-arylation
Copper-catalyzedtandemreactions of 1-(2-haloaryl)-enones with isocyanides for the synthesis of 4-oxoindeno[1,2-b]pyrroles are described. Highly reactive cyclic organocopper intermediates are generated in the copper-catalyzed [3+2]-cycloaddition reactions of isocyanides to double or triple bonds. Successful intramolecular trapping of the organocopper intermediates led to the efficient formation of
描述了铜催化的1-(2-卤代芳基)-烯酮与异氰酸酯的串联反应,用于合成4-氧代茚并[1,2- b ]吡咯。在异氰酸酯的铜催化的[3 + 2]-环加成反应中生成高反应性的环状有机铜中间体,以形成双键或三键。有机铜中间体的成功分子内捕获导致有效形成4-氧代茚并[1,2- b ]吡咯。 铜催化的-异氰化物-烯酮-吡咯
