A series of boronic acid-containing saccharide receptors was synthesised via copper catalysed azide–alkyne cycloaddition (CuAAC) reactions. Their saccharide binding capacity was studied by 1H and 11B NMR spectroscopy titrations and isothermal titra

The exploitable properties of many materials are intimately linked to symmetry-lowering structural phase transitions. We present an automated and exhaustive symmetry-mode method for systematically exploring and solving such structures which will be w

The trans-hydroboration of terminal alkynes mediated by borenium cations [NHC(9-BBN)]+ (NHC = N-heterocyclic carbene, 9-BBN = 9-borabicyclo(3.3.1)nonane) exclusively affords Z-vinylboranes. NHCs and chelating dialkyl substituents on the borenium cati

A number of LnOCuCh (Ln = La–Nd, Bi; Ch = S, Se, Te) compounds have been reported in the literature built from alternating layers of fluorite-like [Ln2O2]2+ sheets and antifluorite-like [M2Se2]2– sheets, where M is in the +1 oxidation state leadi

Since its discovery independently by Sharpless and Meldal in 2002, the copper-catalyzed azide–alkyne cycloaddition (CuAAC) has become a ubiquitous molecular linking platform. Easy access to substituted 1,4-triazoles can be exploited to engender asy

A versatile route to 1,2,5-trisubstituded γ-lactams with tertiary alcohol functionality at the 3-position, from homoallylic amine derivatives with a methyl group at the β-position, is presented.

Aza-conjugate addition of the lithium anion of N-trimethylsilyl-p-methoxybenzylamine to tert-butyl enoate acceptors, in the presence of a stoichiometric amount of enantiopure 1,2-dimethoxy-1,2-diphenylethane and excess trimethylsilyl chloride, afford

A protocol to access useful 4-aminopyrrolidine-2,4-dicarboxylate derivatives has been developed. A variety of chiral N,O-ligands derived from 2,3-dihydroimidazo[1,2-a]pyridine motifs have been evaluated in the asymmetric 1,3-dipolar cycloaddition of

The covalent boron-diol interaction enables elaborate design of boronic acid-based saccharide sensors. Over the last decade, this research topic has been well developed thanks to the integration of boronic acid chemistry with a range of techniques, i
