  • Azoles are important synthetic targets due to their diverse applications in areas ranging from human health to food security. Now it has been shown that the hydroazolation of alkenylthianthrenium salts provides a modular platform to access diverse, densely functionalized N-alkyl azole compounds with high N-regioselectivity.

  • Lewis acids have recently been shown to enable stereocontrol in photochemical cycloadditions, a difficult task due to the reactivity of excited-state compounds. Here the authors show that chiral Brønsted acids are competent chromophore activators in [2+2] cycloadditions, forming diastereomers disfavored in similar Lewis acid catalyzed photochemical reactions.

  • Traditional synthesis of stereodefined piperidines requires selective installation of functional groups that can lower efficiency and modularity. Here, the authors assemble stereochemically complex and highly substituted dehydropiperidines via an intermolecular ring expansion between bicyclic aziridines and Rh-supported vinyl carbenes.
