Disclosed herein are compounds of Formula (I) which inhibit, regulate and/or modulate tyrosine kinase receptors, particularly Axl and Mer signal transduction pathways related to the changes in cellular activities, compositions containing the compounds, methods of using the compounds to treat kinase-dependent diseases and conditions, and methods for making the compounds.
98% ee using a strong Brønsted acid as the activator. This methodology was applied in the facile synthesis of biologically active products containing a chiral indoline skeleton. The mechanism of Pd-catalyzed asymmetric hydrogenation was investigated as well. Isotope-labeling reactions and ESI-HRMS proved that an iminium salt formed by protonation of the C═C bond of indoles was the significant intermediate
Preparation and optimization of new 4-(2-(indolin-1-yl)-2-oxoethyl)-2-morpholinothiazole-5-carboxylic acid and amide derivatives as potent and selective PI3Kβ inhibitors
In our continuous efforts to identify and develop novel targeted cancer treatments, a new morpholino-thiazole scaffold active against PI3Kβ has been identified. This Letter reports the optimization of this compound class to develop PI3Kβ isoform-selective inhibitors with suitable pharmacological properties.

activation mode, we report a new catalytic system for the transfer hydrogenation of naphthols. In the presence of the Pd/C catalyst and base, various naphthols reacted with indolines to afford N-aryl-substituted heterocyclic compounds. Indolines were found to act as novel hydrogen donors for naphthols under palladium catalysis. This method features good functional tolerance, operational simplicity, and a readily
