Improved method for the iodination of sydnones

Iodination at the sydnone C-4 position has been achieved in good yields for a series of 3-arylsydnones using N-iodosuccinimide in acetic acid. Taylor & Francis Group, LLC.

The sydnone ring as an ortho-director of lithiation. Dilithiation of 3-phenylsydnone and trapping by electrophiles

Readily available 3-phenylsydnone (3) reacts with n-butyllithium/TMEDA to form the dilithio species 4 which can be trapped with suitable electrophiles. This represents the first use of a mesoionic ring system for directed lithiation.
