The Pd(OAc)2/CuI system effectively catalyzes the coupling of 3-bromoquinolin-2(1H)-ones with a series of azoles to give 3-(heteroaryl)quinolin-2(1H)-ones in good yields.
the simplified 3‐aminoquinolein‐2‐one analogue 2 b (6BrCaQ), which manifests micromolar activity against a panel of cancer cell lines. The molecular signature of Hsp90 inhibition was assessed by depletion of standard known Hsp90 client proteins. Finally, processing and activation of caspases 7, 8, and 9, and the subsequent cleavage of PARP by 6BrCaQ, suggest stimulation of apoptosis through both extrinsic

study concerning 6BrCaQ analogues as C-terminal Hsp90 inhibitors, we designed and synthesized a novel series of 3-(heteroaryl)quinolin-2(1H), of types 3, 4, and 5, as a novel class of analogues. A Pd-catalyzed Liebeskind–Srogl cross-coupling was developed as a convenient approach for easy access to complex purine architectures. This series of analogues showed a promising biological effect against MDA-MB231
Palladium-Catalyzed Coupling of<i>N</i>-Aminoazoles with 3-Halo-Substituted Quinolin-2(1<i>H</i>)-ones, Coumarins, Quinoxalin-2(1<i>H</i>)-ones, and Chromenes
An efficient and general palladium-catalyzedcoupling of 3-bromoquinolin-2(1H)-ones, 3-bromocoumarins, 3-chloroquinoxalin-2(1H)-ones, and 3-iodo-2H-chromenes with a variety of 1-aminoazoles is described. The reaction proceeds cleanly in the presence of the Pd(OAc)2/4,5-bis(diphenylphosphino)-9,9-dimethylxanthene (Xantphos) catalytic system to provide the coupling products in good to excellent yields
