Copper-catalyzed asymmetric dearomative azidation of tryptamines using azidobenziodoxolone as an azidating reagent was developed, which affords a variety of 3a-azido-pyrroloindolines in good to high enantioselectivities under mild reaction conditions. The azides could be readily transformed into the corresponding 3a-amino-pyrroloindolines reduction and 1,2,3-triazole derivatives a click reaction.

- A new method for nitrating electron-rich arenes using copper as a catalyst has been developed.
- The process involves trimethylsilyl chloride and guanidine nitrate, resulting in a range of nitrated products with yields between 32-99%.
- This reaction can be performed easily at room temperature without the need for harsh acids or complex setups.
