Antimicrobial Peptide‐Peptoid Macrocycles from the Polymyxin B2 Chemical Space

Angewandte Chemie, EarlyView.
We optimized mixed peptide‐peptoid sequences for molecular similarity to the macrocyclic lipopeptide antibiotic polymyxin B2 (PMB2) using a genetic algorithm. Synthesis and testing of top‐scoring compounds allowed us to identify new macrocycles with similar antimicrobial activity and reduced toxicity compared to PMB2.

Continuous Flow Synthesis of Nitrofuran Pharmaceuticals Using Acetyl Nitrate

Angewandte Chemie, EarlyView.
A robust, automated continuous flow system enables safe, high‐yield nitration of furfural to key nitrofuran intermediates using in situ acetyl nitrate generation. Demonstrated on representative essential World Health Organization (WHO) active pharmaceutical ingredients (API), this innovative open‐source platform ensures rapid synthesis, enhanced safety,

Nitrogen Insertion via Asymmetric Condensation and Chirality Transfer: A Stereodivergent Entry to Cyanocyclopropanes

Angewandte Chemie, EarlyView.
The synthesis of cyanocyclopropanes is achieved via asymmetric nitrogen insertion into prochiral cyclobutanones. Key mechanistic steps involve an organocatalyzed asymmetric condensation followed by chirality transfer via an intercepted Neber rearrangement.

PPh3/Isocyanide and N2/Isocyanide Exchange: Pathways to Isolable Alkali Metal Keteniminyl Anions

Angewandte Chemie, EarlyView.
The synthesis of isolable keteniminyl anions through substitution of the phosphine ligand in metalated ylides or the N₂ ligand in diazomethanides with isocyanides is reported. The anions feature a bent geometry, with the angle decreasing with increasing donor ability of the nitrogen substituent, and exhibit broad applicability in the formation of ...
