We report a solvent-directed and regioselective carbon–carbon bondcleavage of aryl ketones by azido-1,3,5-triazines (ATs), which is typically completed within 10 min in DMSO at room temperature, without using transition metal catalysts. The cleavage is driven by the steric hindrance in the adducts of aryl ketones and ATs, which is substantiated by DFT calculation. Our recent results showed that ATs

The first synthesis of novel fused pyridazines has been realized starting from 1,3-diketones involving a Diaza–Wittig reaction as a key step. A convenient strategy was elaborated to access versatile pyridazinederivatives allowing the variation of substituents at position 6 of the heterocyclic ring. In a first part, pyridazines bearing an ester group were synthesized as a model to evaluate the methodology

The first example of enzyme-catalyzed dynamic covalent kinetic resolution of hemithioketals was demonstrated. This method involved the reversible nucleophilic addition of methyl thioglycolate to activated ketones in conjugation with lipase mediated lactonization, generating 1,3-oxathiolan-5-ones in high yields as well as high enantiomeric purities.
