Abstract: A new methodology for N-exocyclic functionalization of iminosydnones was developed involving the addition of a large variety of nucleophiles on carbonyl-imidazolium-activated iminosydnones. This practical and highly versatile method provided access to new classes of iminosydnones… read more here.

DOI: 10.1021/acs.orglett.3c01355
Abstract: Intramolecular electro-oxidative addition of enamines or amides to nonactivated alkynes was attained to access carbonyl-pyrroles or -oxazoles from N-propargyl derivatives. Organoselenium was employed as the electrocatalyst, which played a crucial role as a π-Lewis acid… read more here.
