The invention provides compounds of formula (I), pharmaceutical compositions comprising such compounds and methods of using such compounds to treat or prevent diseases or disorders associated with abnormal or deregulated TRK kinase activity. wherein: and the rest of the variables are as specified in the claims.
Compounds of general formula (I); or a stereoisomers, tautomers, pharmaceutically acceptable salts, or prodrugs thereof, wherein R1, R2, R3, R4, R5, R6, R8 and R9 are as defined herein, are useful for the treatment of diseases and conditions which are mediated by excessive or inappropriate Hsp90 activity such as cancers, viral infection and inflammatory diseases or conditions.
A regioselective formal [4 + 2] cycloaddition for the assembly of highly functionalized benzene rings was successfully developed. In this reaction, olefinic C–H bond functionalization/cyclization cascadereaction followed by rearomatization led to the desired molecules in one step under mild reaction conditions. This protocol also displays a broad substrate scope and good tolerance to a wide range
A DYKAT die hard: A new class of chiral BiSO‐P ligands were effective for an unprecedented palladium‐catalyzed asymmetricallylicalkylation of indoles with the racemic title acetates through a dynamickineticasymmetrictransformation (DYKAT). The hydrogen bond formed between the sulfinyl group of the ligand and NH of indole plays an important role in the reaction.

Cascading ketones! The first highly efficient asymmetric cross‐cascade reaction of different α,β‐unsaturated ketones catalyzed by an easily prepared bulky primary amine salt has been developed. It affords the corresponding diverse products containing three to four contiguous stereocenters with excellent enantio‐ and diastereoselectivities (see scheme).
