Abstract
A method for cobalt-catalyzed, aminoquinoline-directed ortho-functionalization of sp(2) C-H bonds with alkenes has been developed. Reactions proceed at room temperature in trifluoroethanol solvent, use oxygen from air as an oxidant, and require Mn(OAc)3 as a cocatalyst. Benzoic, heteroaromatic, and acrylic acid aminoquinoline amides react with ethylene as well as mono- and disubstituted alkenes affording products in good yields. Excellent functional group tolerance is observed; halogen, nitro, ether, and unprotected alcohol functionalities are compatible with the reaction conditions.

Abstract
![]()
A Rh-catalyzed
C–H bond activation/alkenylation/electrocyclization
cascade reaction provides diverse 1,2-dihydropyridines from simple
and readily available precursors. The reaction can be carried out
at low (<1%) Rh-catalyst loadings, and the use of the robust, air-stable
Rh precatalyst, [RhCl(cod)]2, enables the cascade reaction
to be easily performed on the benchtop. The 1,2-dihydropyridine products
serve as extremely versatile synthetic intermediates for further elaboration
often without isolation. The addition of electrophiles under kinetic
or thermodynamic conditions provides a wide range of iminiums. Subsequent
addition of a nucleophile then generates a diverse array of differently
substituted piperidine products. Additionally, [3 + 2] and [4 + 2]
cycloadditions of the 1,2-dihydropyridine intermediate provides access
to bridged bicyclic structures such as tropanes and isoquinuclidines.
These concise reaction sequences enable the formation of highly substituted
piperidines in synthetically useful yields with excellent diastereoselectivity.

Abstract
N-Enoxyphthalimides undergo a Rh(III)-catalyzed C-H activation initiated cyclopropanation of electron deficient alkenes. The reaction is proposed to proceed via a directed activation of the olefinic C-H bond followed by two migratory insertions, first across the electron-deficient alkene and then by cyclization back onto the enol moiety. A newly designed isopropylcyclopentadienyl ligand drastically improves yield and diastereoselectivity.

Abstract
In the title compound, C26H26N2O2, the piperidine ring exhibits a chair conformation. The phenyl rings are attached to the central heterocycle in an equatorial position. The dihedral angle between the planes of the phenyl rings is 57.58 (8)°. In the crystal, C—H⋯O interactions connect the molecules into zigzag chains along [001].

Abstract
![]()
Appropriately
substituted 2-alkenylphenols undergo a mild
formal [3C+2C] cycloaddition with alkynes when treated with
a Rh(III) catalyst and an oxidant. The reaction, which involves the
cleavage of the terminal C–H bond of the alkenyl moiety and
the dearomatization of the phenol ring, provides a versatile and efficient
approach to highly appealing spirocyclic skeletons and occurs
with high selectivity.

Abstract
Sulfone derivatives are important synthetic intermediates. However, the general method for their preparation is through traditional coupling reaction: the alkylation of sodium sulfinates with phenacyl halides. Based on our previous work on sodium sulfinates and oxime acetates, we herein report a novel method for sulfone derivatives by oxidative coupling with sodium sulfinates and oxime acetates using copper as catalyst. The sulfonylvinylamine products could be formed in excellent yields. Upon hydrolysis by silica gel in CH2 Cl2 , β-ketosulfones could also be efficiently constructed. Various sulfonylvinylamines and β-ketosulfones were obtained in good to excellent yields under the optimized reaction conditions. Mechanistic studies indicated that this transformation involved copper-catalyzed N-O bond cleavage, activation of a vinyl sp(2) C-H bond, and C-S bond formation. The oxime acetates act as both a substrate and an oxidant, thus the reaction needs no additional oxidants or additives.

Abstract
![]()
α,β-Unsaturated carboxylic
acids undergo Rh(III)-catalyzed decarboxylative coupling with α,β-unsaturated O-pivaloyl oximes to provide substituted pyridines in good
yield. The carboxylic acid, which is removed by decarboxylation, serves
as a traceless activating group, giving 5-substituted pyridines with
very high levels of regioselectivity. Mechanistic studies rule out
a picolinic acid intermediate, and an isolable rhodium complex sheds
further light on the reaction mechanism.
