Abstract
A new three-component reductive arylation of amides with stable reactants (iPrOH and arylboronate esters), making use of a 2-pyridinyl (Py) directing group, is described. The N-Py-amide substrates are readily prepared from carboxylic acids and PyNH2 , and the resulting N-Py-1-arylalkanamine reaction products are easily transformed into the corresponding chlorides by substitution of the HN-Py group with HCl. The 1-aryl-1-chloroalkane products allow substitution and cross-coupling reactions. Therefore, a general protocol for the transformation of carboxylic acids into a variety of functionalities is obtained. The Py-NH2 by-product can be recycled.

Abstract
RhIII - and IrIII -catalyzed asymmetric C-H functionalization reactions of arenes have relied on the employment of chiral RhIII /IrIII cyclopentadienyl catalysts, the introduction of chiral carboxylic acids to achiral Cp*RhX2 catalysts, and the integration of both strategies. Despite considerable progress, each reaction only provided a specific configuration of the enantioenriched product when using a particular chiral catalyst. Reported in this work is the enantiodivergent coupling of sulfoximines with various diazo compounds by RhIII -catalyzed desymmetrizing annulation. The enantiodivergence was enabled by a judicious choice of achiral carboxylic acids, and the enantioselectivity correlates with the steric bias of the carboxylic acid and the sulfoximine.

Abstract
A three-component cascade reaction is described that provides concise access to 6H-benzo[c]chromenes via Rh(iii)-catalyzed annulation of aryl ketone O-acyloximes, quinones and acetone. Acetone acts as a co-solvent and as a reactant. This reaction shows high efficiency, atom- and step-economy, good substrate scope, excellent functional group compatibility and gives the products in good yields.
