Journal of the Brazilian Chemical Society, 1999 We describe in this paper the action of trifluoroacetic acid, trifluoromethanesulfonic acid and aluminum chloride upon ortho-substituted aryl azides to form indoles, azepines and arylamines in good yields.

Synthesis of Versatile DNA‐Conjugated Aldehydes by Controlled Oxidation of Amines
Angewandte Chemie, EarlyView.A controlled oxidation strategy enables efficient in situ generation of aldehyde‐functionalized DNAs from DNA‐conjugated amines using O2/laccase/TEMPO. This approach facilitates reversible amine–aldehyde transformations for DNA bioconjugation, and provides access to chemically diverse DNA‐encoded libraries, broadening the toolbox for chemical biology ...

Angewandte Chemie, EarlyView.The highly selective acylative (dynamic) kinetic resolution of racemic paracyclophanols catalysed by a chiral isothiourea (5 mol%) is described (up to s = 50 at 49% conversion or up to 98:2 er and 96% yield in 30 examples). Rotational barriers were analysed for paracyclophanols and selected ester products.

Angewandte Chemie, EarlyView.Aziridination of alkenes is an important route to chiral nitrogen‐containing building blocks. We report that carbamate‐functionalized allylic alcohols undergo highly enantioselective aziridination using achiral dimeric Rh complexes ion‐paired with cinchona alkaloid‐derived chiral cations.
