Optically active or racemic compounds represented by the formula ##STR1## where R.sub.2 is OA and R.sub.3 is selected from the group consisting of H and OA; where A is H or is selected from the group consisting of hydrocarbyl radicals comprising between 1 and 3 carbon atoms, as well as ##STR2## with the proviso that when R.sub.3 is OA, then R.sub.2 and R.sub.3 may be bonded together to form the group R.sub.4 is selected from the group consisting of alkyl and aromatic residues having from 1 to 20, preferably from 1 to 12, carbon atoms, for example, alkyl, optionally substituted with aromatic residues, and aromatic residues optionally substituted with alkyl radicals; n is an integer from 1 to 4; R.sub.5 is an unbranched alkyl chain comprising from 1 and 3 carbon atoms or a cyclopropylmethyl radical; R.sub.1 is alkoxy, cycloalkoxy and a cyclic ether of the formula ##STR3## where m is an integer from 3 to 5; with the proviso that when R.sub.1 is alkoxy, then R.sub.3 cannot be H; and pharmaceutically-acceptable salts thereof. These compounds are useful for alleviating Parkinsonism, glaucoma, hyperprolactinemia and for inducing weight loss in mammals.
光学活性或拉氏混合物由以下式表示##STR1##其中R.sub.2为OA,R.sub.3选自由H和OA组成的群,其中A为H或选自由1到3个碳原子的烃基基团,以及##STR2##但要注意,当R.sub.3为OA时,R.sub.2和R.sub.3可能结合在一起形成R.sub.4为选自由1到20个碳原子的烷基和芳香基团的群,最好为1到12个碳原子,例如,烷基,可选择地用芳香基团替代,以及可选择地用烷基基团替代的芳香基团;n为1到4的整数;R.sub.5为由1到3个碳原子组成的直链烷基链或环丙基甲基基团;R.sub.1为烷氧基,环烷氧基和下式的环醚##STR3##其中m为3到5的整数;但要注意,当R.sub.1为烷氧基时,R.sub.3不能为H;及其药用可接受的盐。这些化合物对于缓解帕金森症、青光眼、高催乳素血症以及诱导哺乳动物体重减轻是有用的。
