Bis-Bromine-1,4-Diazabicyclo[2.2.2]Octane (Br2-DABCO) as an Efficient Promoter for One-Pot Conversion of N-Arylglycines to N-Arylsydnones in the Presence of NaNO2/Ac2O Under Neutral Conditions
Bis‐Bromin‐1,4‐diazabicyclo[2.2.2]octane (Br2‐DABCO)‐promoted one‐pot conversion of various N‐arylglycines to sydnones using a combination of NaNO2 and Ac2O has been achieved efficiently through N‐nitrosation followed by cyclization in high yields (90‐96%) under mild and neutral conditions. Bis‐Brom...
