Allenamides participate as two-carbon components in an intermolecular (2 + 2 + 2) cycloaddition with alkenes and aldehydes when treated with catalytic amounts of a phosphite gold complex. The reaction is highly regio- and chemoselective, and works with different types of alkenes, including...
Remote functionalization of hydrocarbons could be achieved through successive zirconocene-mediated allylic C–H bond activations followed by a selective C–C bond cleavage. Determination of the reaction mechanism by density functional theory (DFT) calculations shows that the high stereocontrol...
An extensive database of spectroscopic properties of molecules from ab initio calculations is used to design molecular complexes for use in tandem solar cells that convert two photons into a single electron–hole pair, thereby increasing the output voltage while covering a wider spectral range....
We report the first examples of highly luminescent di-coordinated Pd(0) complexes. Five complexes of the form (Pd(L)(L′)) were synthesized, where L = IPr, SIPr or IPr* NHC ligands and L′ = PCy 3 , or IPr and SIPr NHC ligands. The photophysical properties of these complexes were determined in...
Photochemical CO 2 reduction catalysed by trans (Cl)–Ru(bpy)(CO) 2 Cl 2 (bpy = 2,2′-bipyridine) efficiently produces carbon monoxide (CO) and formate (HCOO − ) in N , N -dimethylacetamide (DMA)/water containing (Ru(bpy) 3 ) 2+ as a photosensitizer and 1-benzyl-1,4-dihydronicotinamide (BNAH)...
We have performed theoretical analyses of the photophysical properties of a series of cyclometalated gold( iii ) arylacetylide complexes, ((C^N^C)Au III C&z.tbd;CPh-4-OMe), with different extents of π-conjugation at the doubly C-deprotonated (C^N^C) ligand via replacement of one of the phenyl...
Developing approaches to discover protein–protein interactions (PPIs) remains a fundamental challenge. A chemical biology platform is applied here to identify novel PPIs for the AAA+ superfamily oncoprotein reptin. An in silico screen coupled with chemical optimization provided Liddean, a...
The cell wall of pathogenic mycobacteria is abundant with virulence factors, among which phenolic glycolipids (PGLs) are prominent examples. Mycobacterium kansasii , an important opportunistic pathogen, produces seven PGLs and their effect on the release of important proinflammatory cytokines...
It is well-recognized that the failure of many chemotherapeutics arises due to an inability to induce apoptosis. Most cancers acquire a myriad of pro-survival adaptations, and the vast heterogeneity and accumulation of multiple often unrelated anti-apoptotic signaling pathways have been a major...
Iron is essential for eukaryotic biochemistry. Systematic trafficking and storage is required to maintain supply of iron while preventing it from catalysing unwanted reactions, particularly the generation of oxidising reactive species. Iron dyshomeostasis has been implicated in major...
