  Aerobic, Metal-Free, and Catalytic Dehydrogenative Coupling of Heterocycles: En Route to Hedgehog Signaling Pathway Inhibitors

  摘要：

  The nitrosonium ion-catalyzed dehydrogenative coupling of heteroarenes under mild reaction conditions is reported. The developed method utilizes ambient molecular oxygen as a terminal oxidant, and only water is produced as byproduct. Dehydrogenative coupling of heteroarenes translated into the rapid discovery of novel hedgehog signaling pathway inhibitors, emphasizing the importance of the developed methodology.

  A Pincer Ruthenium Complex for Regioselective C–H Silylation of Heteroarenes

  摘要：

  A pincer Ru(II) catalyst for the highly efficient undirected silylation of O- and S-heteroarenes with (TMSO)(2)MeSiH and Et3SiH is described, producing heteroarylsilanes with exclusive C2-regioselectivity, good functional group tolerance, and high turnover numbers (up to 1960). The synthetic utility of the silylated products is demonstrated by Pd-catalyzed Hiyama-Denmark cross-coupling under mild conditions. One-pot, two-step silylation and coupling procedures have been also developed.

  Synthesis of Heterocycles with MF/Al 2 O 3 Base-Systems: 2-Arylbenzofuranes and 2,3-Diarylisoquinolin-1(2H)-ones2-Benzyloxybenzaldehydes, -acetophenones and -benzophenones substituted in the benzyl part with electron-withdrawing groups, cyclize easily to 2-arylbenzofuranes by using a standardized KF- or CsF-Al2O3 base system. An efficient one-pot synthesis for 2,3-diarylisoquinolin-1(2H)-ones is possible by reacting a variety of arene carbaldehyde anils with phthalides under the same reaction conditions.
