Tetrahydrofuran derivatives I, in racemic or enantiomeric form, <IMAGE> (n = 1 to 10, R = C1-C10 alkyl, heteroaryl, or a group of the formula <IMAGE> in which each of R1, R2, R3, R4 and R5 independently represents H, halogen, C1-C5 alkoxy or C1-C5 alkylsulphonyl) and salts thereof are agonists of beta -adrenergic receptors, and may thus be useful as bronchodilators. |
