The present invention relates to N-substituted heterocyclic derivatives of formula: ##STR1## processes for their preparation, and pharmaceutical compositions which contain them. The compounds according to the invention are non-peptide compounds which oppose the action of angiotensin II. The compounds according to the invention are thus useful in the treatment of cardiovascular disorders such as hypertension and heart failure.
both nucleophilic and electrophilic centers, and their arylation reactions are known to proceed at N(sp3) and C(sp) sites, leading to N-aryl cyanamides or amidines. N(sp) selectivity has also been reported only in the presence of amines, thus leading to guanidines. Herein, we report a general copper-catalyzed ligand-controlled Chan-Lam-Evans arylation of cyanamides proceeding regioselectively at the N(sp3)
