New intermediate compounds are disclosed of the formula I, ##STR1## wherein R.sub.1 and R.sub.2 are independently alkyl having 1 to 4 carbon atoms, or acid-addition salts thereof of formula Ib, ##STR2## wherein X represents an acid residue, and a process for the preparation of the intermediate compounds.

Racemic and optically active octahydro-indolo(2,3-a) tetrahydropyranyl

An antifungal or anthelmintic method of treatment is disclosed which comprises the step of administering to a mammal in need of said treatment, a pharmaceutically effective amount of a compound of the Formula (I) ##STR1## wherein X is halogen, C.sub.1 to C.sub.6 alkoxy, or a group --NRR.sup.1 in which R and R.sup.1 are each hydrogen or C.sub.1 to C.sub.6 alkyl; and

Aminodiaryl sulfoxide derivatives, process for their preparation and

The invention relates to a new process for the preparation of nitraminodiaryl sulfoxide derivatives of the formula (I), ##STR1## wherein R and R.sup.1 represent hydrogen or alkyl having from 1 to 6 carbon atoms, and

Nitraminodiaryl sulfoxide derivatives, process for their preparation and

The invention relates to a new process for the preparation of aminodiaryl sulfoxide derivatives of the formula (I), ##STR1## wherein X is halogen, alkoxy having from 1 to 6 carbon atoms or a group --(N,R,R.sup.1), in which p1 R and R.sup.1 are hydrogen or alkyl having from 1 to 6 carbon atoms,

Process for the preparation of nitrodiaryl sulfoxides

The invention relates to new eburnane derivatives of the formula (I) ##STR1## wherein R.sup.1 is alkyl having from 1 to 6 carbon atoms, and acid addition salts thereof. The invention further relates to a process for the preparation of these compounds and pharmaceutical compositions containing them. Compounds of formula (I) show remarkable CNS-activity and are useful intermediates in the preparation of other, pharmaceutically active compounds.

Eburnane derivatives, process for their preparation and pharmaceutical

The invention relates to new racemic and optically active apovincaminic acid derivatives of the general formula (I) ##STR1## wherein A is hydroxyl, halogen or a group --O--(CH.sub.2).sub.n --OR.sup.1 or --OMe, in which
