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).

Homogeneous Pd catalysts have been identified for the conversion of cyclohexenone and tetralone O-pivaloyl oximes to the corresponding primary anilines and 1-aminonaphthalenes. This method is inspired by the Semmler-Wolff reaction, a classic method that exhibits limited synthetic utility owing to its forcing conditions, narrow scope, and low product yields. The oxime N-O bond undergoes oxidative addition to Pd-0(PCy3)(2), and the product of this step has been characterized by X-ray crystallography and shown to undergo dehydrogenation to afford the aniline product.
