[The beta-adrenolytic activity of new arylmethyloxypropanolamine analogs of dioxadilol].

: A series of arylmethyloxypropanolamines structurally related to Dioxadilol has been synthesized and tested for their beta adrenolytic activity. Only one compound, the benzofuranic derivative 3c, exhibited a similar activity as Dioxadilol but was less potent than propranolol.
