Die Verbindungen der Formel 1 werden nach an sich bekannten Verfahren erhalten, insbesondere wie folgt:The compounds of formula 1 are per se obtained, in particular as follows:

  • 1. Umsetzung einer Verbindung der Formel (worin Het, R4, A und B die obige Bedeutung haben und R bevorzugt für einen C1-C4-Alkylrest oder für Benzyl steht) mit Ammoniak in einem Alkohol, wie Methanol, Ethanol, n-Propanol, i-Propanol, oder in einem inerten Lösungsmittel, etwa Dichlormethan, Tetrahydrofuran, Dioxan, bei Temperaturen zwischen etwa 0 und 50°C, vorzugsweise bei etwa 20°C.1.

(wherein A, B, Het, X 1 , X 2 and R 4 are as defined above and L is a nucleofugic leaving group, Z is OH or SH).

Die Umsetzung erfolgt in Lösungsmitteln wie Dimethylsulfoxid, Dimethylformamid, Acetonitril oder Alkoholen wie Methanol, Ethanol oder Propanol unter Zusatz einer Base (Metallcarbonate, Metallhydroxide, Metallhydride) bei Temperaturen zwischen etwa 0 und 140°C bzw. der Siedetemperatur des Reaktionsgemischs.The reaction takes place in solvents such as Dimethylsulfoxide, dimethylformamide, acetonitrile or alcohols such as methanol, ethanol or propanol with the addition of a base (metal carbonates, Metal hydroxides, metal hydrides) at temperatures between about 0 and 140 ° C or the boiling point of the reaction mixture.

Die Phenole oder Thiophenole können auch in Form von Salzen, etwa der Alkalisalze, eingesetzt werden. Als nucleofuge Abgangsgruppe eignen sich z. B.

Auch die Umsetzung der Nitrile mit H2S in Lösungsmitteln wie Pyridin oder Dimethylformamid in Gegenwart einer Base wie Triethylamin und anschließende Alkylierung bzw. Benzylierung führen zu Verbindungen der Formel V. Ausgehend von Carbonsäureamiden, die im übrigen den Verbindungen der Formel V entsprechen, gelangt man auch durch Umsetzung mit einem Trialkyloxoniumsalz wie Triethyloxoniumtetrafluoroborat in einem Lösungsmittel wie Dichlormethan, Tetrahydrofuran oder Dioxan bei Temperaturen zwischen 0 und 50°C, vorzugsweise bei Raumtemperatur zu Verbindungen der Formel V.(wherein A, B, Het and R 4 have the above meaning) prepared, which in turn can be obtained, for example, analogously to the reaction according to method 3. The further synthetic route consists in the implementation of the corresponding nitriles with HCl over the stage of the imide chlorides or the direct reaction with z. B. C 1 -C 6 alcohols or benzyl alcohol in the presence of an acid such as HCl. The reaction of the nitriles with H 2 S in solvents such as pyridine or dimethylformamide in the presence of a base such as triethylamine and subsequent alkylation or benzylation lead to compounds of the formula V. Starting from carboxylic acid amides, which otherwise correspond to the compounds of formula V, one arrives also by reaction with a Trialkyloxoniumsalz such as Triethyloxoniumtetrafluoroborat in a solvent such as dichloromethane, tetrahydrofuran or dioxane at temperatures between 0 and 50 ° C, preferably at room temperature to compounds of the formula V.
