Abstract It has been found that the novel tetrahydronaphthalene derivatives of the formula Image I wherein R1 to R6 and n have the significance given in claim 1. have a pronounced activity in counteracting cerebral insufficiency or improving cognitive functions and also reduce the multiple-resistance towards cytostatics in the treatment of tumours or of chloroquine resistance in the treatment of malaria. They can accordingly be used as medicaments, especially for the control or prevention of cerebral insufficiency or for the improvement of cognitive functions. The novel compounds of formula I can be manufactured by O-acylating a likewise novel compound of the formula Image II.
