Diarylethene‐Containing Photoswitchable Analogues of Tubulysins—Design, Synthesis, Biological, and Structural Evaluation

European Journal of Organic Chemistry, EarlyView.
Diarylethene‐containing cyclic tubulysin analogues were designed, synthesized, and evaluated as light‐responsive cytotoxic agents. One analogue showed reversible photoswitching, photoregulated tubulin polymerization inhibition, and photoform‐dependent cytotoxicity.

A Straightforward Synthesis of Benzestrol by Matteson Homologation Using Chiral Benzyl Carbamates

European Journal of Organic Chemistry, EarlyView.
Benzestrol can easily be obtained stereoselectively via Matteson reaction using chiral Boronic esters and chiral benzyl carbamates. A straightforward and highly stereoselective synthesis of the non‐steroidal estrogen benzestrol is described based on Matteson homologations.

Unified Approach for the Synthesis of Close Analogues of Reverse‐Prenylated Hexahydropyrrolo Indole Alkaloids

European Journal of Organic Chemistry, EarlyView.
A simple, modular, and unified strategy for the synthesis of reverse‐prenylated hexahydropyrrolo indole alkaloids has been developed. An unusual retrosynthetic disconnection allows for the late introduction of a side chain, which distinguishes many members of this class of natural products.

The continuing significance of chiral agrochemicals

Pest Management Science, Volume 81, Issue 4, Page 1697-1716, April 2025.
In the time frame 2018–2023, around 43% of the 35 chiral agrochemicals introduced to the market (herbicides, fungicides, insecticides, acaricides, and nematicides) contain one or more stereogenic centers in the molecule, and almost 69% of them have been marketed as racemic mixtures of enantiomers or stereoisomers.

University teaching of mass spectrometry as a key practical technique within the context of a fully integrated, spiral curriculum

Rapid Communications in Mass Spectrometry, EarlyView.
Rationale Mass spectrometry (MS) is introduced to high school students in the UK in many pre‐university course syllabi. As such, we have identified the use of MS as a key technique that should be taught practically to undergraduates from the outset of their studies.
