The preparation and pharmacological properties of ψ-corbasil

Abstract
The synthesis is described of threo-α-methyl noradrenaline (ψ-corbasil). The assignments of the erythro and threo configurations to corbasil and ψ-corbasil respectively are supported by the evidence of the nmr spectra. Some preliminary results are reported for the relative pharmacological activity of the two isomers at α- and β-adrenergic receptors.
