New chiral and isomeric cyclopropyl ketoxime propanolamine derivatives with potent β-adrenergic blocking properties

Article abstract of DOI:10.1021/jm00145a008

The synthesis of R-(+) and s-(-)isomers of O-[3-(tert-butylamino)-2-hydroxypropyl] cyclopropyl methyl ketone oxime (falintolol) is described. The syn and anti isomers of falintolol were obtained in two different ways from cyclopropyl methyl ketoxime or from falintolol. For comparison purposes, the enantiomers of the dicyclopropyl ketone oxime derivatives were also prepared. Structure-activity relationships are described.
