    摘要: New geminally disubstituted indenes are of general formula I ##STR1## wherein each of R.sup.1 and R.sup.2 is hydrogen or R.sup.1 and R.sup.2 together form a direct bond or an alkylene group --(CH.sub.2).sub.n --, in which n is an integer from 1 to 4, R.sup.3 is hydrogen, C.sub.1-3 -alkoxy or halogen, and each of R.sup.4 and R.sup.5 is hydrogen or C.sub.1-4 -lower alkyl, or R.sup.4 and R.sup.5 together form an alkylene group --(CH.sub.2).sub.m --, in which m is an integer from 3 to 6; and the corresponding amine oxides, quaternary ammonium compounds and salts with physiologically acceptable acids.The indenes find use in treating incontinence, as a mucous membrane decongestant, as a blood pressure reducing agent, as vasocostrictor or as an anti-reserpine agent.The indenes may be prepared by processes known per se involving(a) synthesing the side chain --CH(OH)CH.sub.2 NR.sup.4 R.sup.5 by a method known per se in an indenyl precursor of a formula I compound in which the side chain is incomplete or(b) introducing the double bond into an indanyl precursor of a formula I compound in which the double bond is absent or(c) releasing the terminal amino group in a precursor of a formula I compound in which the terminal amino group is protected.
