6-(N-Substituted amino)-3-arylcyclohex-2-enol (7) was designed as a new type of β-adrenergic blocker on the basis of the X-ray crystallographic data for propranolol. Eight such compounds (7) were prepared by a six-step sequence of reactions from 3-arylcyclohex-2-enone (8), and tested for β-blocking activity in vitro. A weak β-blocking activity was exhibited by 6-(1-methyl-3-phenylpropyl) amino-3-phenylcyclohex-2-enol (7e).

A novel protocol has been developed for the Cu-catalyzed synthesis of primary arylamines with meta-substituents using cyclohexenone oxime esters. Mechanistic insights suggest that the reaction proceeds via an intermolecular 1,5-H hydrogen atom transfer of an imine radical intermediate. This approach features high efficiency, a readily available catalyst system, and broad functional group tolerance
