(IC50 > 5 μM), while 3e–g, 5a, 5c–e, 5g, 7a, and 7d showed a moderate activity (IC50 ≥ 0.05 μM). Compounds (5b, 5f, 7b, and 7c) showed significant activity (IC50 < 1.0 μM); thus, their anticancer activities were carried out. Anticancer activity was found to be selective towards breast cancer (MCF‐7); 5b, 5f, 7b, and 7c showed predominant relative percentage activities of 74.12%, 79.04%, 72.56%, and 78.47%, with

palladium(0)‐catalyzed amidation of heteroaromatic tosylates was successfully developed. The methodology proved to be effective for a variety of heteroaryl tosylates including the pyridine, pyrimidine, quinoline and quinoxaline ring systems. Successful carbonnitrogen bond formation with these heteroaryl tosylates could be performed with a wide range of primary amides, oxazolidinones, lactams, anilines and

Mg for B: An atom‐economical one‐potsynthesis by direct magnesium insertion in the presence of B(OBu)3 and LiCl allows a broad range of functionalized (hetero)aryl and alkenyl bromides to be converted into magnesium diorganoboronates 2, which undergo Suzuki–Miyauracross‐couplingreactions with various aryl (pseudo)halides (see scheme). Both aryl groups of 2 are transferred and furnish the products
