Abstract A Rh(I)‐catalyzed C6‐selective C−H arylation of 2‐pyridones with inexpensive, readily available, safe and structurally diverse aryl carboxylic acids with the aid of a pyridine directing group is developed. This decarbonylative arylation protocol features an easy‐to‐handle catalytic system, and is amenable to diversely substituted 2‐pyridones and aryl carboxylic acids. It allows access to a wide range of C6‐arylated 2‐pyridones, including those that are difficult to prepare using conventional C−H arylation processes. The method tolerates various electron‐neutral, electron‐rich and electron‐deficient functional groups, and affords the products in 41–91% yields. magnified image

Visible Light‐Assisted Direct C−H Acyloxylation of Polycyclic Aromatic Hydrocarbons using Carboxylic Acids
Abstract The direct C−H acyloxylation of polycyclic aromatic hydrocarbons (PAHs) with carboxylic acids as the acyloxylating agents was achieved via the electron‐donor‐acceptor (EDA) complexes between PAHs andN‐iodosuccinimide (NIS). This visible light‐assisted metal‐free C−H acyloxylation reaction provides an easy access to the desired aryl carboxylates from readily available PAHs and aliphatic and aromatic carboxylic acids under mild reaction conditions. magnified image

Abstract A Rh(II)/Au(I) catalyzed carbene cascade approach for the stereoselective synthesis of diverse spirocarbocycles is described. The cascade reaction involves a rhodium carbene initiatedsp2C−H functionalization followed by a gold catalyzed Conia‐ene cyclization. The cascade reaction accommodates a variety of aryl substituents as well as ring sizes and proceeds with high diastereoselectivity providing access to diverse spirocarbocycles. magnified imagemore » « less

Abstract The diastereodivergent synthesis of bridged 1,2,3,4‐tetrahydroisoquinoline derivatives has been achieved by using appropriate modularly designed organocatalysts (MDOs) that are self‐assembled in situ from amino acids and cinchona alkaloid derivatives. The domino Mannich/aza‐Michael/aldol reaction between (E)‐2‐[2‐(3‐aryl‐3‐oxoprop‐1‐en‐1‐yl)phenyl]acetaldehydes and ethyl or benzyl (E)‐2‐[(4‐methoxyphenyl)imino]acetates catalyzed by MDOs gives two different diastereomers of the desired bridged tetrahydroisoquinolines in good yields and excellent diastereoselectivities (up to 99:1 dr) and enantioselectivities (up to >99%ee). The diastereodivergence was achieved in the aldol reaction step. magnified imagemore » « less

Abstract The direct formation of aryl C−O bonds via the intramolecular dehydrogenative coupling of a C−H bond and a pendant alcohol represents a powerful synthetic transformation. Herein, we report a method for intramolecular arene C−H etherification via an umpoled alcohol cyclization mediated by an I(III)N‐HVI reagent. This approach provides access to functionalized chromane scaffolds from primary, secondary and tertiary alcohols via a cascade cyclization‐iodonium salt formation, the latter providing a versatile functional handle for downstream derivatization. Computational studies support initial formation of an umpoled O‐intermediate via I(III) ligand exchange, followed by competitive direct and spirocyclization/1,2‐shift pathways. magnified imagemore » « less

Abstract The design of catalysts for asymmetric propargylations remains a challenging task, with only a handful of methods providing access to enantioenriched homopropargylic alcohols. In this work, guided by previously reported computational predictions, a set of atropisomeric bipyridineN,N’‐dioxides was tested as Lewis base catalysts for the asymmetric propargylation of aldehydes with trichloroallenylsilane. The catalysts are easily prepared in four simple steps starting from readily available methyl ketones. Aryl‐substituted derivatives proved to be highly active and showed a high level of enantiocontrol even at 1 mol% loading. The reaction scope includes a wide range of aromatic, heteroaromatic, and unsaturated aldehydes. New computations confirm that the key stereodetermining transition state structures for the synthesized catalysts are similar to those previously reported for the model structure. magnified imagemore » « less
