title: Synthesis of potential adrenergic blocking agents: 2-substituted aminomethylnaphthol(2,3-b)-1,4-dioxans.
abstract: Eleven 2-substituted aminomethylnaphtho(2,3-b)-1,4-dioxans were synthesized. The nucleophilic displacement of 2-tosyloxymethylnaphtho(2,3-b)-1,4-dioxan by appropriate amines was carried out using dimethyl sulfoxide as the solvent. Preliminary pharmacological evaluation revealed a potentiation of norepinephrine at low doses and a noncompetitive antagonism at high doses in the rat vas deferens and a dose-related hypotensive action of short duration in the anesthetized rat.
