4-disubstituted chromene derivatives, whereas the analogous coupling with cyclic enones yielded 9-hydroxybenzoxazole products. The reaction of 3,5-dimethoxyphenol with PhCH═CHCDO resulted in the chromene product with a significant H/Dexchange to both benzylic and vinyl positions. The most significant carbon isotope effect from the coupling of 3,5-dimethoxyphenol with 4-methoxycinnamaldehyde was observed
ne烯和苯并氧杂环衍生物是通过苯酚与α,β-不饱和羰基化合物的钌催化脱水CH-H偶联反应有效合成的。发现阳离子钌氢化物络合物是有效的催化剂,可用于苯酚与烯类的偶联和环化,形成苯并二氢萘产品。苯酚与线性烯酮的偶合得到2,4-二取代的色烯衍生物,而与环烯酮的类似偶合产生9-羟基苯并恶唑产物。3,5-二甲氧基苯酚与PhCH = CHCDO的反应生成的苯并二氢萘产物在苯甲基和乙烯基位置均具有显着的H / D交换。3的偶合最显着的碳同位素效应 在色烯产物的α-烯烃碳上观察到5-二甲氧基苯酚与4-甲氧基肉桂醛(C(2)= 1.067)。3,5-二甲氧基苯酚与对位取代的p -XC 6 H 4 CH = CHCHO表现出线性相关性,并具有吸电子基团(ρ= +1.5; X = OCH 3,CH 3,H,F,Cl)的强促进作用。通过催化偶合法合成了几种具有生物活性的色酮衍生物。该催化方法提供了一种方便的合成方

Disclosed herein are methods of activating expression of the FOXO3 gene in a subject comprising administering to a subject small molecule compound (such as astaxanthin and/or one or more astaxanthin derivatives), or pharmaceutically acceptable salts thereof, in an amount sufficient to at least partially increase the amount of FoxO3 expressed in the subject.
of the reactions of the flavyliumion 1a and the 4′-methoxyflavylium ion 1b with various π-nucleophiles and tributylstannane were investigated photometrically in dichloromethane. Electrophilicity parameters E(1a) = −3.46 and E(1b) = −4.96 were derived from the equation log k (20 °C) = s(E + N); these allow the prediction of potential reaction partners of the flavyliumions 1a and 1b.

Basic flavonoid (flavene) and neoflavonoid (neoflavene) skeletons were successfully synthesized using ring-closingmetathesis, showing that this methodology can be used as a central synthetic tool for the synthesis of at least two of the three basic flavonoid classes.
