The inventive indene derivatives of formula (I) are capable of selectively modulating the activities of peroxisome proliferator activated receptors (PPARs), causing no adverse side effects, and thus, they are useful for the treatment and prevention of disorders modulated by PPARs, i.e., metabolic syndromes such as diabetes, obesity, arteriosclerosis, hyperlipidemia, hyperinsulinism and hypertension, inflammatory diseases such as osteoporosis, liver cirrhosis and asthma, and cancer.

Chiral polyvinylpyrrolidinone (CSPVP), complexes of CSPVP with a core species, such as a metallic nanocluster catalyst, and enantioselective oxidation reactions utilizing such complexes are disclosed. The CSPVP complexes can be used in asymmetric oxidation of diols, enantioselective oxidation of alkenes, and carbon-carbon bond forming reactions, for example. The CSPVP can also be complexed with biomolecules such as proteins, DNA, and RNA, and used as nanocarriers for siRNA or dsRNA delivery.
A rhenium complex, [ReBr(CO) 3 (thf)] 2 , catalyzes the insertion of α,β-unsaturated carbonyl compounds into a C-H bond of aromatic compounds having nitrogen-containing directing groups. In this reaction, Re 2 (CO) 10 can also be used as a catalyst. When imines are employed as the aromatic substrates, sequential cyclization proceeds and indene derivatives are obtained in good to excellent yields. This

successfully applied to a broad range of substrates, producing 1H-indenes in good to excellent yields. The metallo-radical catalyzed indene synthesis in this paper represents a unique example of a net (formal) intramolecular carbene insertion reaction into a vinylic C(sp(2))-H bond, made possible by a controlled radical ring-closure process of the carbene radical intermediate involved. The mechanism was investigated
提出了一种通过邻肉桂基 N-甲苯磺酰腙的金属基活化催化合成取代 1H-茚的新策略,利用 Co(III) 卡宾自由基中间体的固有反应性。该反应使用容易获得的起始材料并且操作简单,因此代表了构建官能化1H-茚衍生物的实用方法。廉价且易于制备的低自旋钴 (II) 配合物 [Co(II)(MeTAA)](MeTAA = 四甲基四氮杂 [14] 环烯)被证明是所研究的催化剂中最活跃的催化剂,它证明了催化卡宾自由基反应性非卟啉钴 (II) 络合物,以及 [Co(II)(MeTAA)] 的首次催化活性。该方法已成功应用于广泛的基材,以良好到极好的收率生产 1H-茚。本文中金属自由基催化的茚合成代表了一个独特的例子,即净(正式)分子内卡宾插入反应成乙烯基 C(sp(2))-H 键,通过受控自由基闭环过程使之成为可能。卡宾自由基中间体参与其中。通过计算研究了该机制,并通过一系列支持实验反应证实了结果。密度泛

coupling partners in Pd-catalyzed cross-couplingreactions. A variety of allyl acetates such as but-1-en-3-yl acetate, crotyl acetate, and 2-methylallyl acetate afforded the corresponding allylic compounds in good yields in cross-couplingreactions. Various electrophilic cross-coupling partners such as aryl iodides and vinyl bromides and triflates participate in these reactions. Not only intermolecular but
