Modular Approach to Heterogenous Catalysis. Manipulation of Cross-Coupling Catalyst Activity
摘要:
A new type of robust, heterogeneous, modular Pd catalyst with metal embedded in the gel matrix is presented. The regulatory element of its catalytic activity has been introduced via chemical changes in the gel. The concept is illustrated in a series of Suzuki-Miyaura cross-coupling reactions. The demonstrated catalyst activity variations depend on the structure of the gel.

Compounds of Formulas Ia and Ib, and stereoisomers, geometric isomers, tautomers, solvates, metabolites and pharmaceutically acceptable salts thereof, are useful for inhibiting receptor tyrosine kinases and for treating disorders mediated thereby. Methods of using compounds of Formula Ia and Ib, and stereoisomers, geometric isomers, tautomers, solvates and pharmaceutically acceptable salts thereof, for in vitro, in situ, and in vivo diagnosis, prevention or treatment of such disorders in mammalian cells, or associated pathological conditions are disclosed.

substrates with α,β‐unsaturated ketones has been optimized, providing a facile route towards aliphatic ketone products. When employing α,β‐unsaturated aldehydes as coupling partners, under the optimized protocol, a cascade reaction forming azepinones has also been developed. Finally, DFT studies have demonstrated how stabilization of a metallo‐enol intermediate when employing α,β‐unsaturated ketones is
已对具有α,β-不饱和酮的苯甲酰胺底物的Cp * Co III催化的CH-H官能化进行了优化,从而提供了一条通往脂肪族酮产品的简便途径。当使用α,β-不饱和醛作为偶联伙伴时,在优化方案下,还形成了形成a庚酮的级联反应。最后,DFT研究表明,当使用α,β-不饱和酮时,金属烯醇中间体的稳定化是导致观察到的脂肪族酮产物而不是使用α,β-不饱和酯作为偶联伙伴的烯烃产物的驱动力。

A rhodium(III)-catalyzed direct dehydrogenative annulation of benzamides with alkynes through chelating-assisted CH activation has been developed. Naphthylamide and isoquinolinone derivatives can be chemoselectively obtained by this protocol.
The present invention relates to certain compounds (e.g., imidazopyrazine, imidazopyridine, imidazopyridazine and imidazpyrimidine compounds) that act as inhibitors of the MAP kinase interacting kinases MNK2a, MNK2b, MNK1a, and MNK1b. The present invention further relates to pharmaceutical compositions comprising these compounds, and to the use of the compounds for the prevention and treatment of diseases (e.g., proliferative diseases (e.g., cancer), inflammatory diseases, autoimmune diseases, metabolic diseases, and neurodegenerative diseases (e.g. autism, autism spectrum disorders, Alzheimer's disease)), as well as methods of treating these diseases
