Cobalt‐catalyzed CH arylations enabled the synthesis of biaryl tetrazoles, which are key structural motifs in antihypertensive angiotensin‐II‐receptor blockers. Thus, weakly‐coordinating benzamides were employed for step‐economical CH arylations with ample scope. Further, a low‐valent NHC complex enabled first cobalt‐catalyzed CH functionalization by tetrazole assistance.

The invention is related to compound which comprises at least one radical C═Y, Y being O or S, and an oxidable and non protonable nitrogen atom N wherein the distance (d) between the at least one carbon atom of the radical group C═Y and the nitrogen atom, when oxidized, is comprised between 0.3 and 0.8 nanometers. The invention is related to new heterocyclic compounds defined by formula G, their preparation, to pharmaceutical compositions comprising them and to their use as therapeutic agents, particularly in the treatment of neurodegenerative or Alzheimer disease.
