By employing reusable nanocobalt oxides as the catalysts, a site-specific oxidative C–H chalcogenation of (hetero)aryl-fused cyclicamines with various thiols and diselenides is presented for the first time. The reaction proceeds selectively at the sites of the (hetero)aryl rings para to the N atom, and enables access to a wide array of chalcogenyl N-heteroarenes. The merits of the transformation involve

the direct one-pot synthesis of tetrahydroquinoline derivatives from amino alcohols and ketones has been also developed on the basis of the continuous catalytic activity of this rutheniumcatalyst in the selective hydrogenation of the obtained quinoline derivatives with a low catalyst loading. The corresponding products, quinolines and tetrahydroquinoline derivatives, were afforded in good to excellent

A compound of formula (I): or a pharmaceutically acceptable salt thereof, wherein: R1 is H, Cl, F, CH3 or CF3; R2 is H, C1-C6 alkyl or optionally substituted heteroaryl or optionally substituted aryl; and R3 is (Alk)n-Rn-(Alk)n-Rn-(Alk)n-X. The compounds are useful as tetrahydroisoquinoline (THQ) compounds, which are suitable for use as PDK inhibitors, for example for inhibition of cancer cell proliferation.

Catalytic acceptorless dehydrogenation (CAD) has been a basically important organic transformation to ubiquitous unsaturated compounds without the usage of a sacrificial hydrogen acceptor. In this work, we successfully developed the first electrochemical acceptorless dehydrogenation (ECAD) of N-heterocycles using TEMPO as the organo-electrocatalyst. We have achieved the catalyticdehydrogenation of

acceptorless dehydrogenation is an environmentally benign way to desaturate organic compounds. This process is traditionally accomplished with transition‐metal‐based catalysts. Herein, a borane‐catalyzed, metal‐free acceptorless dehydrogenation of saturated N‐heterocycles is disclosed. Tris(pentafluorophenyl)borane was identified as a versatile catalyst, which afforded several synthetically important N‐heteroarenes
