to ketones is highly desirable yet challenging in organic synthesis. We herein report the first Ni/bis-NHC-catalyzed cross-coupling of N-acylpyrrole-type amides with arylboronic esters to obtain diarylketones. This method is facilitated by a new chelating bis-NHC ligand. The reaction tolerates diverse functional groups on both arylamide and arylboronic ester partners including sensitive ester and ketone
A series of aroylquinoline derivatives were synthesized and evaluated for anticancer activity. 5-Amino-6-methoxy-2-aroylquinoline 15 showed more potent antiproliferative activity (IC50 values ranging from 0.2 to 0.4 nM) as compared to 1a (combretastatin A-4) (IC50 = 1.9-835 nM) against various human cancer cell lines and a MDR-resistant cancer cell line. Compound 15 (IC50 = 1.6 mu M) exhibited more potent inhibition of tubulin polymerization than 1a (IC50 = 2.1 mu M) and showed strong binding property to the colchicine binding site of microtubules.
