New aspects of catalytic intramolecular C-H amination: Unexpected formation of a seven-membered ring in nitrogen-containing systems

The first example of the formation of a seven-membered ring by way of intramolecular-catalyzed amination of saturated C-H bonds is reported (Du Bois reaction). The influence of various structural parameters was studied, and it was shown that the unexpected regioselectivity observed in nitrogen-containing systems could be rationalized by conformational factors. These results open the way to innovative strategies for the general synthesis of polyfunctionalized piperidines.
