CH25050An unusual triterpene fatty acid conjugate from Dodonaea caespitosa

Andrew M. Bloomfield 0000-0003-4449-6872, Eugene Eades, Hendra Gunosewoyo 0000-0003-3897-1948 and Alan D. Payne 0000-0003-4530-6348
 

Chemical structure of the betulin conjugate 2 extracted from Dodonaea caespitosa.

The south-west of Western Australia is a biodiversity hotspot, where collaborations between local communities and scientists play a pivotal role in the study of native plants. The leaf resin of Dodonaea caespitosa, growing in Nowanup, contained only two compounds, one of which was an unusual bioconjugate comprising a triterpene, a cutin monomer and a p-hydroxycinnamate. This natural product was the first isolated to date and will help our understanding of the biology and ecology of this plant. (Image credit: Andrew M. Bloomfield.)

CH25003Friedel–Crafts chemistry. Part 64. Facile syntheses of fused azepinoindoles by Jourdan–Ullmann and Friedel–Crafts approaches

Hassan A. K. Abd El-Aal 0000-0003-4158-6960
 

Friedel–Crafts cyclisations of indole carboxylic acids or indole alcohols to tetracyclic azopinoindoles.

Indole fused N-heterocycles form the structural core of a large number of natural products and pharmaceuticals. These properties make them exciting targets for synthetic chemists, with a wide range of synthetic methodologies reported. However, these often have a number of drawbacks, including cost, scalability and low yields. Herein, we explore an efficient construction of benzo-, pyrido-, thieno-, naphtho-fused azepinoindolones and indolo-azepinoquinolinones from readily available starting materials through Lewis and Brønsted acid mediated Friedel–Crafts reactions.

CH25070The value of telling it like it was. The best honours project ever?

Cartoon by Sidney Harris of a reviewer of a chemical process saying ‘I think you should be more explicit here in step two’ where it says ‘Then a miracle occurs’

Undergraduate students should appreciate that chemical understanding is not static; what we teach is our ‘best guess’ to explain observables. Textbooks frequently conflate (and often incorrectly describe) the concept of the nucleus, inferred by Rutherford from Marsden’s ‘gold foil’ experiment, with the model of the nucleus, containing protons and neutrons, despite nearly 25 years between these advances. We argue that an opportunity is lost in the teaching of chemistry, to illustrate to students the incremental progress in chemistry and that the ‘wrong’ explanation can be very useful.

CH25059The development of a bioassay expressing the human MRGPRX2 receptor for ex vivo drug discovery

Jan Tytgat 0000-0003-1778-6022
 

Illustration of the action of a venom on MRGPRX2. The GIRK1/2 channel opens, generating a flow of inward K current.

Mast cells of our immune system are generally difficult and expensive to maintain in vitro and, therefore, not economical to use in drug discovery. The development of a bioassay expressing the human mas-related G protein-coupled receptor-X2 receptor linked to potassium channels in a host cell offers a good alternative.

CH25030The cooperative effect of CPC micelles and RuIII on the rate enhancement of L-tyrosine oxidation by N-bromosuccinimide

Conceptual illustration of RuIII-catalysed oxidation of L-Tyr by NBS in an acidic CPC micellar medium.

In the CPC micellar environment, the more hydrophobic reactant component (L-Tyrosine) and the extended aliphatic chain of CPC reside in the micelle’s core. The micelle Stern layer preserves the polar components of the surfactant (Me3N+), substrate (–NH2, and –COOH) and reactive species of NBS and RuIII in proximity, hence promoting the oxidation of L-Tyr. The elevated concentration of reactant molecules at the micellar interface enhances the effective collision frequency among the reacting molecules, significantly promoting the oxidation process.

A schematic of how phenols react with DMAD in the presence of phosphine or NHC as catalyst to give aryl vinyl ethers by the Michael reaction

The catalytic activities of triphenylphosphine and N-heterocyclic carbene, namely 3-benzyl-4,5-dimethylthiazolylidene, have been compared by carrying out oxa–Michael additions of some phenols with dimethyl acetylenedicarboxylate in the presence of one of these catalysts. The experimental results have been rationalised on the basis of theoretical calculations. (Image credit: Priyanka Suthar.)

The compounds present in Psidium guajava L. were evaluated against three different proteins (PDB ID: 4A79, 7E3H, 7F61) associated with the regulation of neurodegenerative diseases. Using a computational approach, these compounds were tested for their capability to inhibit the proteins. The resultssupport the potential of P. guajava compounds in managing neurodegenerative disorders. (Image credit: the authors.)

CH25006closo-Borate aryliodonium zwitterions: convenient intermediates for functional closo-borane derivatives and molecular materials

Piotr Kaszynski 0000-0002-2325-8560
 

Schematic of the functionalization of closo-borates through aryliodonium zwitterions.

This review summarizes the formation, structure, stability and reactions of aryliodonium zwitterions of closo-borate anions. The zwitterions are formed by regioselective aryliodination of closo-borates with ArIII reagents and undergo efficient reactions with nucleophiles. Therefore, this tandem of reactions represents an effective regioselective activation of the B–H bonds in closo-borates towards nucleophilic substitution. (Image credit: Piotr Kaszyński.)

Reaction scheme for the ring-expansion of Cyrene with ethyl diazoacetate and subsequent decarboxylation.

Levoglucosenone and the reduced analogue Cyrene are versatile chiral intermediates for synthesis, available from the cellulose fraction of biomass by acid-catalysed pyrolysis. An ethyl diazoacetate mediated ring expansion has been developed for Cyrene, and combination with a decarboxylation has resulted in homologated ring-systems. Some selected reactions for the first homologated ring-system were then investigated. (Image credit: Ben Greatrex.)
