This invention relates to novel benzospiran derivatives embraced by the formula ##STR1## wherein the sum of A and B is at least the integer 2; A is selected from the group consisting of --(CH.sub.2).sub.n wherein n is 1 through 5 and --(CH.sub.n H.sub.2n --.sub.2 XY)-- wherein X is selected from the group consisting of hydroxy, acetoxy, amino and acetamido and Y is hydrogen, and X when taken together with Y is selected from the group consisting of =O and =CR.sup.3 R.sup.4 wherein R.sup.3 and R.sup.4 are selected from the group consisting of hydrogen and lower alkyl of 1 through 3 carbon atoms; B is absent or --(CH.sub.2).sub.n wherein n is 1 through 3; R.sup.1 is selected from the group consisting of hydrogen and lower alkyl of 1 through 3 carbon atoms; R.sup.2 is selected from the group consisting of hydrogen, lower alkyl of 1 through 3 carbon atoms, ##STR2## WHEREIN N IS 2 THROUGH 5 AND Ar is phenyl having zero through three substituents selected from the group consisting of lower alkyl of 1 through 3 carbon atoms, lower alkoxy of 1 through 3 carbon atoms, bromine, chlorine and fluorine; R.sup.1 and R.sup.2 taken together with --N< is a saturated heterocyclic amino radical selected from the group consisting of unsubstituted and substituted pyrrolidino, piperidino, and hexamethylenimino; Z is selected from the group consisting of hydrogen, lower alkyl of 1 through 3 carbon atoms, lower alkoxy of 1 through 3 carbon atoms, nitro, amino, monoalkylamino of 1 through 3 carbon atoms, acylamido of 1 through 4 carbon atoms, bromine, chlorine and fluorine; and a pharmacologically acceptable acid addition salt thereof. It also relates to intermediates and processes for the preparation of the aforesaid novel compounds (1) and novel derivatives thereof. The administration to humans and animals of the novel compounds (1) depresses their central nervous systems and lowers their blood pressures.
