Had a wonderful time at the group BBQ yesterday. It once again reminded me that I do not "just" have the pleasure to work with excellent scientists, but also a group of amazing persons. Thanks to everyone who contributed! #chemsky #proudPI

Table of contents graphic showing the reaction of an aliphatic carboxylic acid with a styrene to give a γ-vinylidene lactone via tripple C-H functionalization. The structure of the ligand used is given as well as bullet points showing the main strenghts of the report, such as a broad substrate scope.

Great job Edis and @sourjyamal.bsky.social! Their work on the synthesis of γ-Alkylidene Lactones has just been accepted for publication in the @rsc.org journal @chemicalscience.rsc.org

Taken together with a subsequent reaction with amine the method enables the generation of a sulfonamide library from a sincle secondary sulfonamide and may prove highly useful in the variation of lead structures in medicinal chemistry.

A table of contents graphic showing the direct conversion of a generic secondary sulfonamide to the respective sulfonylfluoride and a subsequent diversification to varied sulfonamides. Highlights of the method are listed as bullet points: Aromatic and aliphatic sulfonamides; efficient diversification method; commercially available reagent; high functional group tolerance; operationally simple; scalable.

Congratulations to Friedrich Jurk, whose manuscript "Mild and Efficient Synthesis of Sulfonyl Fluorides from Sulfonamides Enabled by Diethylaminosulfur Trifluoride" has been accepted for publication in Synlett. doi.org/10.1055/a-26...

Just saw on the OL homepage that the article currently leads the journals most read list, thanks for all the interest in our work! pubs.acs.org/action/showM...

Indeed got confused, thanks for the correction.

Great step by the RSC. Next important one would be to sort out the Elon Musk issue.

Direct Pd-Catalyzed β-C(sp3)–H Hydroxylation of Aliphatic Carboxylic Acids β-Hydroxy carbonyl scaffolds are of paramount importance due to their presence in a variety of natural products and bioactive molecules. In this study, we present a direct palladium-catalyzed β-C(sp3)–H hydroxylation of aliphatic carboxylic acids. The reported method employs convenient and readily available TBHP as an oxidant and provides an efficient, one-step route to a diverse range of β-hydroxy acids. Key aspects include the compatibility of this method with challenging α-non-quaternary carboxylic acids as substrates and excellent functional group tolerance. This newly developed method is expected to prove useful for generating compound libraries relevant to multiple disciplines.

Five years after reporting the direct acyloxylation of carboxylic acids, we could now finally achieve the direct hydroxylation, just out in Org. Lett. Huge congratulations to @sourjyamal.bsky.social and Tianxiao Xu!

Had two brilliant presentations in our @gdch.de seminar this week by Masilamani Jeganmohan from IIT Madras and Phillip Heretsch from @unihannover.bsky.social bith with great insights to #OrganicChemistry. Many thanks to both guests for sharing their research!

📢 Today’s highlight: editors from @synthesis1969.bsky.social and @synlettjournal.bsky.social are visiting University of Padova and giving fantastic talks.

✨ If you are nearby, come and see! It is a great chance to connect, learn, and be inspired.

Last week three new group members joined our group: Varvara Fomenko, Celia Sanchez Gonzalez and Dr. Aleksei Zerov 🧪 we are looking forward for exciting research 🤓

Huge congradulations to Dr. Tianxiao Xu on successfully defending his PhD! 🥳👨🏻‍🎓 We wish you all the best for your future endeavours. You will be missed dearly!

You are right: Enantiomers have equal solubility in achiral solvents regardless of polarity. However, solubility of racemates and enantiopure compounds typically differ, the basis of purification via crystallization. Also, diastereomers of course can have different solubility.
