Angewandte Chemie, Volume 138, Issue 16, 13 April 2026.It may seem counterintuitive to first target a ruthenium alkylidyne when Grubbs‐type ruthenium carbene complexes are the actual goal. In the end, however, this tactic pays valuable dividends in terms of practicality, atom economy, flexibility as well as safety: the new route provides ready access to a large assortment of catalysts for alkene metathesis

1,3-Dipolar cycloadditions of azomethine imines [PDF]
, 2015 Azomethine imines are considered 1,3-dipoles of the aza-allyl type which are transient intermediates and should be generated in situ but can also be stable and isolable compounds.

The FEBS Journal, EarlyView.Characterization of anhydromevalonate phosphate decarboxylase, the UbiD‐family decarboxylase involved in the archaeal mevalonate pathway, was conducted. The enzyme is responsible for the biosynthesis of isoprenoids, such as archaeal membrane lipids, respiratory quinones, and dolichols.

1,3-dipolar cycloadditions of aldehydes or Imines with carbonyl ylides generated from epoxides: Classical heating and microwave irradiation [PDF]
, 2007 International audienceCycloadditions of aldehydes with carbonyl ylides to give dioxolanes have been carried out without solvent under microwave irradiation. The reactions proceeded in similar yields and stereoselectivities, but in shorter reaction times,

Journal of Physical Organic Chemistry, Volume 39, Issue 6, June 2026.The dithiirane–thiosulfine equilibrium has been revisited by means of modern computational chemistry tools to shed light on whether stable thiosulfines might be isolated. ABSTRACT Thiosulfines as reactive S‐centered 1,3‐dipoles undergoing (3 + 2)‐cycloadditions are still of interest in the chemistry of sulfur‐rich heterocycles.
