Abstract
An endo-directing group strategy enables enantioselective (3+1+2) cycloadditions that are triggered by carbonylative C-C bond activation of cyclopropanes. These processes are rare examples of cycloadditions where C-C bond oxidative addition is enantiodetermining, and the first where this is achieved within the context of a multicomponent (higher order) reaction design.

Abstract
![]()
Under Rh-catalyzed
conditions, secondary amines and anilines function
as directing groups to facilitate regioselective C–C bond activation
of nonactivated cyclopropanes. The resulting amino-stabilized rhodacycles
undergo carbonylative C–N bond formation en route to challenging
seven- and eight-membered lactams. The processes represent rare examples
where C–C bond oxidative addition of nonactivated cyclopropanes
is exploited in reaction design.

Abstract
Multitasking single-catalyst systems that allow multiple chemical transformations within a single reaction vessel are important for the development of eco-compatible chemistry. Here, we have developed a rhodium-catalyzed system that transforms 1-(allyloxy)-2-(cyclopropylmethyl)benzene derivatives to 2-ethyl-3-isopropylbenzofurans via double isomerization/cycloisomerization/aromatization.

Abstract
The development of a catalytic intramolecular "cut-and-sew" transformation between cyclobutanones and alkynes to construct cyclohexenone-fused rings is described herein. The challenge arises from the need for selective coupling at the more sterically hindered proximal position, and can be addressed by using an electron-rich, but less bulky, phosphine ligand. The control experiment and 13 C-labelling study suggest that the reaction may start with cleavage of the less hindered distal C-C bond of cyclobutanones, followed by decarbonylation and CO reinsertion to enable Rh insertion at the more hindered proximal position.

Abstract
![]()
A modular
Rh-catalyzed entry to azepines is outlined. Under a CO
atmosphere, protecting group directed C–C bond activation of
aminocyclopropanes provides rhodacyclopentanones. These
intermediates are effective for intramolecular C–H metalation
of either an N-aryl or N-vinyl unit en route to azepine ring systems.
Thus, byproduct-free heterocyclizations are enabled by sequential
C–C activation and C–H functionalization steps.

Abstract
A Rh-catalyzed regiodivergent hydrosilylation of acyl aminocyclopropanes has been developed. Acyl aminocyclopropanes were reacted with hydrosilanes in the presence of Rh catalysts to afford ring-opened hydrosilylated adducts through carbon-carbon (C-C) bond cleavage of the cyclopropane ring. The regioselectivity of the addition of silanes (linear or branched) can be switched by changing the monophosphine ligand. This C-C bond cleavage/hydrosilylation methodology is applicable to the synthesis of silanediol precursors.

Abstract
The transition metal-catalyzed "cut and sew" transformation has recently emerged as a useful strategy for preparing complex molecular structures. After oxidative addition of a transition metal into a carbon-carbon bond, the resulting two carbon termini can be both functionalized in one step via the following migratory insertion and reductive elimination with unsaturated units, such as alkenes, alkynes, allenes, CO and polar multiple bonds. Three- or four-membered rings are often employed as reaction partners due to their high ring strains. The participation of non-strained structures generally relies on cleavage of a polar carbon-CN bond or assistance of a directing group.

Abstract
In this review, synthetic and mechanistic aspects of key methodologies that exploit C-C single-bond cleavage of strained ring systems are highlighted. The focus is on transition-metal-catalyzed processes that are triggered by C-C bond activation and β-carbon elimination, with the review concentrating on developments from mid-2009 to mid-2016.

Abstract
![]()
Under carbonylative conditions, neutral
Rh(I)-systems modified
with weak donor ligands (AsPh3 or 1,4-oxathiane) undergo
N-Cbz, N-benzoyl, or N-Ts directed insertion into the proximal C–C
bond of aminomethylcyclopropanes to generate rhodacyclopentanone
intermediates. These are trapped by N-tethered alkenes to provide
complex perhydroisoindoles.

Abstract
Rhodacyclopentanones, an "sp(3)-rich" class of metallacycle, underpin an emerging range of catalytic methodologies for the direct generation of complex scaffolds. This review highlights strategies for accessing rhodacyclopentanones (and related species) by C-C bond activation of cyclobutanones or cyclopropanes. The scope and mechanism of methodologies that exploit these activation modes is outlined.

Abstract
Rhodacyclopentanones derived from carbonylative C-C activation of cyclopropyl ureas can be "captured" by pendant nucleophiles prior to "collapse" to 1,3-diazepanes. The choice of N-substituent on the cyclopropane unit controls the oxidation level of the product, such that C4-C5 unsaturated or saturated systems can be accessed selectively.
