    摘要: The invention relates to optically active or racemic eburnane-oxime ethers of the formulae (Ia) and/or ##STR1## wherein R represents an alkyl group having 1 or 2 carbon atoms,R.sup.2 represents an alkyl group having 1 to 6 carbon atoms,and the configuration of the hydrogen in the 3-position and the R.sup.2 group is .alpha.,.alpha. and/or .beta.,.beta. or .alpha.,.beta. and/or .beta.,.alpha. and acid addition salts thereof.The new compounds show valuable pharmaceutical activities, thus are potent CNS-tranquillants, smooth muscle relaxants, sedatives and hypnotic agents, and can therefore be employed as active ingredients of pharmaceutical compositions, which are also within the scope of the present invention.

    摘要: New compounds of the general formula (I) ##STR1## wherein R stands for an alkyl group, have been prepared by reducing a compound of the general formula (II) ##STR2## wherein R stands for alkyl, B stands for H.sub.2 O or an X.sup.- anion derived from an acid, and if B is an X.sup.- anion, A represents hydrogen, whereas if B is H.sub.2 O, A represents an electron pair. If desired, the racemic compounds of the general formula (I) can be resolved to yield the corresponding optically active isomers. The free bases of the general formula (I) can be converted into their pharmaceutically acceptable salts, or the salts can be treated with an alkaline agent to yield the free bases.The compounds of the general formula (I) can be used in the therapy primarily as vasodilatating agents.

    摘要: New compounds of the general formula (I) ##STR1## wherein R.sub.1 stands for alkyl and R.sub.2 stands for carboxy, a functional carboxy derivative or a group convertible into carboxy group or a functional derivative thereof, have been prepared by reducing a compound of the general formula ##STR2## wherein R.sub.1 and R.sub.2 each have the same meanings as defined above and X.sup.- represents an anion derived from an acid, and optionally subjecting the obtained compound to hydrolysis. If desired, the racemic compounds of the general formula (I) can be resolved to yield the corresponding optically active isomers. The free bases of the general formula (I) can be converted into their pharmaceutically acceptable salts, or the salts can be treated with an alkaline agent to yield the free bases.The compounds of the general formula (I) can be used in the therapy primarily as vasodilatating agents.
