Angewandte Chemie, Volume 138, Issue 5, 28 January 2026.A radical cascade process involving the activation of two aliphatic C–H bonds in a series of five elementary steps converts readily available terminal alkynes into functionalized cyclopentylmethyl arylsulfones. The methodology delivers flexible synthetic intermediates and was applied to the preparation of diquinanes and triquinanes possessing a rare ...

Chemical Methods for Peptide and Protein Backbone Cleavage
ChemistryEurope, EarlyView.Protein cleavage plays essential roles in biology and is powerful for protein manipulation and functionalization as well as in recombinant expression and purification. Here, the historical background and most recent examples of chemical methods for protein and peptide backbone cleavage are discussed (part of the figure was generated in BioRender).

Decaimento de íons cianato e a formação de carbamato de etila
Química Nova, 2013 Cyanate ion stability was studied in aqueous/ethanolic solutions, pH = 4.5 (CH3COOH/NaCH3COO), at different temperatures. Following the decay [(OCN)-] versus time, in the presence of excess C2H5OH, the rate constant for this reaction (k1) was calculated ...
