Controlled Delivery and Light‐Induced Release of Magic Spot Nucleotides in Escherichia coli
Angewandte Chemie International Edition, Volume 65, Issue 15, 6 April 2026.We synthesized photocaged, clickable and isotope‐labeled “magic spot” Nucleotides and delivered them into Escherichia coli comparing different approaches. Light‐controlled release inside living cells enabled tracking of their conversion from pppGpp to ppGpp by capillary electrophoresis mass spectrometry and revealed their impact on the growth rate of a

Concise Synthesis of Tetrazole Macrocycle [PDF]
Organic Letters, 2017 A concise two step synthesis of tetrazole containing macrocycles from readily accessible starting materials is presented. The first step comprises a chemoselective amidation of amino acid derived isocyanocarboxylicacid esters with unprotected symmetrical diamines to afford diverse α-isocyano-ω-amines. In the second step, the α-isocyano-ω-amines undergo
