Bis ‐Bromin‐1,4‐diazabicyclo[2.2.2]octane (Br 2 ‐DABCO)‐promoted one‐pot conversion of various N ‐arylglycines to sydnones using a combination of NaNO 2 and Ac 2 O has been achieved efficiently through N ‐nitrosation followed by cyclization in high yields (90‐96%) under mild and neutral conditions.
