    Organocatalytic Functionalization of Carboxylic Acids: Isothiourea-Catalyzed Asymmetric Intra- and Intermolecular Michael Addition−Lactonizations
    摘要:
    Tetramisole promotes the catalytic asymmetric intramolecular Michael addition-lactonization of a variety of enone acids, giving carbo- and heterocyclic products with high diastereo- and enantiocontrol (up to 99:1 dr, up to 99% ee) that are readily derivatized to afford functionalized indene and dihydrobenzofuran carboxylates. Chiral isothioureas also promote the catalytic asymmetric intermolecular Michael addition-lactonization of arylacetic acids and alpha-keto-beta,gamma,-unsaturated esters, giving anti-dihydropyranones with high diastereo- and enantiocontrol (up to 98:2 dr, up to 99% ee).

    The present invention provides a 4,5-dihydro-1H-pyrazole derivative or its pharmaceutically acceptable salt, a process for the preparation thereof, and a pharmaceutical composition comprising the same. The 4,5-dihydro-1H-pyrazole derivative or its pharmaceutically acceptable salt effectively increases the LXR transcriptional activity, and therefore can be usefully applied for preventing or treating a dysfunction in cholesterol metabolism, such as cholesterol gallstone, hyperlipidemia, or coronary atherosclerosis.

    5-bis(trifluoromethyl)-, bismethyl-, and bisfluoro-phenyl substituents at the 3,3'-position. For the first time, we show that not only chemical stability but also catalytic activity and stereoselectivity of the MOFs can be tuned by modifying the ligand structures. Particularly, the MOF incorporated with -CF3 groups on the pore walls exhibits enhanced tolerance to water, weak acid, and base compared with the MOFs with
    多相催化的一个关键挑战是设计和合成具有高催化活性、选择性和可回收性的多相催化剂。在这里,我们证明了可以通过使用配体设计策略从属有机框架 (MOF) 平台设计高性能多相不对称催化剂。三个具有骨架式 [Mn2L(H2O)2] 的多孔手性 MOF 是由 1,1'-双的对映纯膦酰基羧酸配体制备的,该配体用 3,5-双(三甲基)-、双甲基-和双-官能化苯基取代基在 3,3'-位。我们首次表明,不仅可以通过修饰配体结构来调节 MOF 的化学稳定性,还可以调节其催化活性和立体选择性。特别,与具有 -F 和 -Me 基团的 MOF 相比,在孔壁上引入 -CF3 基团的 MOF 对、弱酸和碱的耐受性更强。在间歇和流动反应系统下,含 的 MOF 表现出优异的反应性、选择性和可回收性,为吲哚吡咯与一系列酮酯或硝基烯烃的烷基化提供高产率和对映选择性。相比之下,相应的均相催化剂在催化测试反应时的

    We described a Ni-bidentate oxazoline catalyzed highly enantio- and diastereoselective decarboxylative aldol reaction of 2-oxotetrahydrofuran-3-carboxylic acid/2-oxochromane-3-carboxylic acid derivatives with different kinds of carbonyls. Under optimal reaction conditions, α-substituted β-hydroxy butyrolactones and dihydrocoumarins with an all-carbon quaternary stereocenter have been generated with

    base-mediated [3 + 3] benzannulation strategy for the conversion of 1,3-bis(sulfonyl)propenes and β,γ-unsaturated α-ketoesters to diaryl sulfones has been developed. This method provides facile, metal-free and efficient access to highly substituted diaryl sulfones in good to excellent yields. In addition, the sulfonyl group could be easily removed or converted to other functional groups via an organostannane
