Synthesis of 2(3H)‐benzoxazolone and 2(3H)‐benzothiazolone derivatives as potential beta‐3‐adrenergic receptor ligands (part 2)

Adrenoceptors beta‐3‐subtype mediate lipolysis and in the search for potential beta‐3‐adrenergic receptors agonists for the treatment of obesity, we designed new arylethanolamines (structures 4, 5 ) and aryloxypropanolamines (structures 6, 7 ) derived from 2(3H)‐benzoxazolone and 2(3H)‐benzothiazolone.
