A New Strategy for the Synthesis of Benzylic Sulfonamides: Palladium-Catalyzed Arylation and Sulfonamide Metathesis
摘要:
[GRAPHICS]An efficient two-step strategy has been developed to access diversely functionalized benzylic sulfonamides. Execution of this strategy required the development of two reaction methods: the palladium-catalyzed cross-coupling of aryl halides with CH-acidic methanesulfonamides and a metathesis reaction between the resulting alpha-arylated sulfonamides and diverse amines. The broad scope of the cross-coupling process combined with a versatile sulfonamide metathesis constitutes an efficient strategy for the synthesis of various benzylic sulfonamides.
The present invention provides compounds and compositions thereof which are useful as inhibitors of plasma kallikrein and which exhibit desirable characteristics for the same.
Compounds of general formula (I), wherein R1, R11, Y, R2, n and A are as defined herein are useful as inhibitors or metallo-β-lactamase (MBL) enzymes and can be used for reducing or removing antibiotic resistance in bacteria.
The present invention relates to 5H-benzo[4,5]cyclohepta[1,2-b]pyridine derivatives, that are useful for treating cellular proliferative diseases, for treating disorders associated with MET activity, and for inhibiting the receptor tyrosine kinase MET. The invention also related to compositions which comprise these compounds, and methods of using them to treat cancer in mammals.
