Versatile directed aromatic C–H bond activation and oxidative coupling with allylicalcohols is reported using a cationic Rh(III) catalyst. This method provides efficient and robust synthesis of functional β-aryl ketones and indolines in good yields with excellent regioselectivity, even the reaction runs at 3 g scale. The catalytic systems have good functional group tolerance, such as CONR2, NHAc,

classes remains unresolved and limitations not fully understood. This study focuses on the translation of an established Cp*Co(III)-catalysed alkylation of benzamides to related acetanilides using 3-buten-2-one as coupling partner. The developed procedure provides a wide substrate scope in terms of substituted acetanilides, although the optimised conditions were found to be more forcing than those for

Neuropeptide S receptor antagonists are provided that bind in functional assays to neuropeptide S receptors; methods are provided for use of these antagonists in treatment of conditions or disease states that are ameliorated by blocking of the neuropeptide S receptor, including substance abuse and substance abuse relapse; and for use of neuropeptide S receptor antagonists in the manufacture of therapeutics and pro-drugs for therapeutics useful in disease states and conditions sensitive to binding of the neuropeptide S receptor.
