A novel series of heteroarylmethoxyphenylalkoxyiminoalkylcarboxylic acids was studied as leukotrienebiosynthesisinhibitors. A hypothesis of structure-activity optimization by insertion of an oxime moiety was investigated using REV-5901 as a starting point. A systematic structure-activity optimization showed that the spatial arrangement and stereochemistry of the oxime insertion unit proved to be

The invention relates to compounds of formula (I): as defined in the application. Such compounds are suitable for the treatment of a disorder or disease which is mediated by the activity of MDM2 and/or MDM4, or variants thereof.
Herein, we describe the generation of an organochromium-type carbanion species from a non-activated C-H bond and its nucleophilic addition to aldehydes. The catalytic carbanion generation occurred through formal deprotonation of a non-activated C-H bond under mild conditions and did not need the prefunctionalization or anion stabilizing group.

developed for the Barbier–Grignard-typealkylationreaction of aldehydes (including aliphatic version) usingunactivatedalkylhalides in water in the presence of an In/CuI/I2 or In/AgI/I2 system. The reactions proceeded more efficiently in water than in organic solvent. In, CuI or AgI, and I2 were all essential for the efficient progress of the reactions. A radical-type reaction mechanism was studied
在In / CuI / I 2或In / AgI / I 2系统存在下,使用未活化的烷基卤化物在水中进行醛的Barbier-Grignard型烷基化反应(包括脂肪族)的有效方法。该反应在水中比在有机溶剂中更有效地进行。In,CuI或AgI和I 2对反应的有效进行都是必不可少的。研究并提出了一种以4-戊烯为底物的自由基型反应机理。

The aqueousBarbier-Grignard-typealkylation of aldehydes with unactivatedalkyl iodides and bromides was developed. By using a combination of zinc and cuprous iodide, catalyzed by indium(I) chloride, we successfully added tertiary, secondary, and primary alkylhalides to various aromatic aldehydes in 0.07 M aqueous Na2C2O4. A mechanistic rationale for the success of the reaction has been proposed
