Thank you very much @gomobel.bsky.social for highliting our work on @chemistryworld.com. Chiral acyl phosphates meet self-assembly..! Thanks also @claudiabonfio.bsky.social and @jeannecrassousiscr.bsky.social for the very nice comments about our work!!

Just out in @ChemRxiv
More than a leaving group!! We show how phosphate leaving groups can regulate reaction pathways and drive orthogonal amide bond formation. Well done Arti!

Click or Acyl transfer? We show how amino acyl phosphates and peptide nucleophiles direct acyl transfer vs click chemistry, enabling temporal control in abiotic networks. Well done

Phase behavior and pathway-selective oligomerization driven by amino acid side-chain recognition What basic ingredients enable amino acid side-chain recognition and assembly without complex biological machinery? We show that even simple molecular sorters can organize amino acids in space and time...

Very cool work!

Congratulations Mahesh for successfully defending your thesis! The first PhD student from the group. An amazing research journey ends here and we wish you all the best for your future research adventures!!

Thank you Oliver!

Thank you Rienk!

Self-assembly of the phosphate esters give rise to covalent self-sorting in oligomerization reactions.

The chemical structures of the phosphate esters can be tailored to direct the synthesis of specific sequences.

We show how side chain reactivity and pre-organisation of phosphate esters can drive selective peptide bond formation from a pool of amino acids.

Selective peptide bond formation via side chain reactivity and self-assembly of abiotic phosphates - Nature Communications In biological processes, peptide bonds are formed via reactive phosphate-containing intermediates, facilitated by compartmentalized environments. Here, the authors use aminoacyl phosphate esters that ...

Happy for our published article in @NatureComms
