Abstract

έθοδος παρασκευής νέων ετεροκυκλικών ενώσεων του γενικού τύπου Ι (όρα φύλλον τύπων), εις τον οποίοντο R1 δηλοί άτομα υδρογόνου ή κατώτερον αλκυλικόνυπόλοιπον ή το βενζυλικόν υπόλοιπον και R2 άτομονυδρογόνου, φθορίου, χλωρίου ή βρωμίου ή κατωτέραναλκυλ- ή αλκοξυ-ομάδα, και των αλάτων τούτων, χαρακτηριζομένη κατά τούτο ότι εν σουξινιμίδιον του γενικού τύπου ΙΙ, εις τον οποίον το R1 έχει την ανωτέρω σημασίαν, φέρομεν εις αντίδρασιν μετά τινος ενώσεως του γενικού τύπου ΙΙΙ, εις τον οποίον το R2έχει την ανωτέρω δοθείσαν σημασίαν και αλογόνου, κατά προτίμησιν χλωρίου ή βρωμίου, επί παρουσία αλκαλικού τινος μέσου συμπυκνώσεως, ενδεχομένως δε μετατρέπομεν το προϊόν της αντιδράσεως εις τα αντίστοιχα άλατα δια κατεργασίας μετ' ανοργάνων ή οργανικών οξέων. A process for the preparation of novel heterocyclic compounds of general formula I (form sheet), wherein R 1 denotes hydrogen atoms or a lower alkyl moiety or the benzyl moiety and R 2 is an atomic hydrogen, fluorine, chlorine or bromo- or lower group, or characterized in that in a succinimide of general formula II, in which R1 has the above significance, it reacts with a compound of general formula III, in which R2 has the above significance and halogen, preferably chloramphenicol. , in the presence of an alkaline concentrate, the reaction product may be converted to the corresponding salts by treatment with inorganic or organic acids.
