    Abstract: A quinoline derivative represented by general formula (1), a medicinally acceptable salt thereof, and a remedy for cardiac diseases containing the same, wherein ring A represents a furan, dihydrofuran or dioxolane ring, R1 represents hydroxy, carboxy, alkoxycarbonyl, etc., R2s may be the same or different from each other and each represents hydrogen, alkyl, etc., R?3 and R4¿ may be the same or different from each other and each represents hydrogen, halogen, alkyl, amino, alkoxy, etc., R?5, R6, R7 and R8¿ may be the same or different from one another and each represents hydrogen or alkyl, m represents an integer of 0 to 3, and symbol ...... means that there may be a double bond formed by R?6 and R8¿. The compound (1) has a positively inotropic effect on myocardia and an antiarrhythmic effect and can dilate blood vessels without extremely increasing the heart rate. Therefore, a remedy for cardiac diseases containing the same as the active ingredient is remarkably useful for treating cardiac insufficiency, arrhythmia, and so forth.

    Abstract: PROBLEM TO BE SOLVED: To obtain a large amount of the subject compound useful as a therapeutic agent for heart diseases under mild conditions in a high yield by treating a specific phthalimide compound with a base. SOLUTION: (2-RS,3-SR)-2,3,5,8,8-Pentamethyl-2-(N-phthaliminomethyl)-2,3,7,8- tetrahydro-6H-furo[2,3-e]indol-7-one of formula I is treated with a base (e.g. methylamine) to give the objective (2-RS,3-SR)-2-aminomethyl-2,3,5,8,8- pentamethyl-2,3,7,8-tetrahydro-6H-furo[2,3-e]indole-7-one of formula II. When an organic amine is used as the base, preferably the compound of formula I is reacted with 1-5 equivalents of the amine at 50-120 deg.C for 1-10 hours. The compound of formula I is preferably obtained by reacting an iodine compound of formula III with a phthalimide alkali salt in an aprotic polar solvent.

    Abstract: PURPOSE:To provide a new pyrano[2,3-f]quinoline derivative having excel lent antiarrhythmic action, cardiac action, vasodilative action, etc., and useful as a cardiac disease therapeutic agent represented by cardiac failures. CONSTITUTION:The compound of formula 1 (R is lower alkyl; R is H, halogen, OH, lower alkylsulfonyloxy, lower alkanoyloxy, lower alkoxy, azido, amino; R is H, lower alkyl; R is H, lower alkyl, OH, lower alkylamino, pyrrolidinyl or piperazinyl which may have a substituent; when a double bond exists between the 3,4 positions, the substituent R does not exist), e.g. 3acetoxy-6-methyl-3,4,7,8- tetrahydro-2H-pyrano[2,3-f]quinoline. The compound of formula 1-1 among the compounds of formula 1 is obtained by reacting a quinoline compound with an allyl halide compound, thermally subjecting the obtained compound of formula 3 to a Claisen rearrangement, reacting the reaction product with an aliphatic acid anhydride, reacting the obtained compound of formula 5 with a peracid, and subsequently treating the produced epoxy compound of formula 6 with an alkali halide.

    Abstract: NEW MATERIAL:A sulfonamide compound shown by the formula (R1 is lower alkyl, lower alkoxy or halogen; R2 is H, lower alkyl, aryl or arylalkyl; R3 is aryl or arylalkyl; R4 and R4' may be the same or different and H, lower alkyl or lower alkoxy; m is 0-3; n is 1-8) and an acid addition salt thereof. EXAMPLE:1-Diphenylmethyl-4-(3-benzenesulfonylaminopropyl)piperazine. USE:Useful as a drug for cardiovascular system. PREPARATION:For example, a compound shown by formula II is reacted with a compound shown by formula III in a solvent such as methylene chloride or chloroform at -10-+100 deg.C, preferably in the presence of a base such as sodium hydroxide to give a compound shown by formula I wherein R2 is H. Further this compound is reacted with a compound shown by the formula R2'Y (R2' is R2 except H; Y is halogen, alkylsulfonyloxy, etc.) and converted to a compound shown by formula I wherein R2 is except H.
