Abstract

έθοδος δια την παρασκευήν Ν1, Ν2-δις υποκατεστημένων υδραξιδίων των καρβονικών οξέων, ως και των αλάτων αυτών, διακρινομένη εκ τούτου ότι την 1,2-διϊσοπροπυλο-υδραζίνην ή εν άλας αυτής, συμπυκνούμεν με εν μέσον ακυλιώσεως παρέχον το υπόλοιπον R-CO-,ένθα το R δηλοί εν ενδεχομένως δι' ατόμων αλογόνου, υδροξυλικών ομάδων, ή ομάδων ακυλοξύ, ομάδων αλκοξύ, ή αλκυλομερκαπτομάδων, περιεχουσών μέχρι 4 ατόμων άνθρακος υποκατεστημένον υπόλοιπον ενός κεκορεσμένου ή ακορέστου κυκλοαλειφατικού υδρογονάνθρακος, εν υπόλοιπον κεκορεσμένου ή ακορέστου, ευθείας ή διακλαδισμένης αλύσου, αλειφατικού υδρογονάνθρακος, ή εν πενταμελές ετεροκυκλικόν υπόλοιπον, ειςην περίπτωσιν το R δηλοί εν υπόλοιπον υποκατεστημένον δι' ομάδων ακυλοξύ σαπωνοποιούμεν τούτο ενδεχομένως προς το αντίστοιχον δι' υδροξυλικών ομάδων υποκατεστημένον υπόλοιπον, το δε λαμβανόμενον υδραζίδιον καρβονικών οξέων μετατρέπομεν ενδεχομένως εις εν άλας. Process for the preparation of N1, N2-bis substituted carbohydrates of carboxylic acids, as well as their salts, characterized in that 1,2-diisopropylhydrazine or a salt thereof is concentrated with an acylating agent to give the remaining R-CO , wherein R denotes, where appropriate, by halogen atoms, hydroxyl groups, or acyloxy groups, alkoxy groups, or alkylmercaptom groups, containing up to 4 carbon atoms, substituted residue of a saturated or unsaturated cycloaliphatic hydrogenate, or aliphatic hydrocarbon, or a five-membered heterocyclic moiety, in the case of R denoted by a moiety substituted by acyloxy groups, possibly saponifying it with the corresponding hydroxyl moiety substituted with the moiety remaining in the acid.
