Abstract

έθοδος δια την παρασκευήν βασικώς υποκατεστημένωνπροπανολών του τύπου: [*] εις τον οποίον το R δηλοί εν άτομον υδρογόνου ή την μεθοξυ-ομάδα, το R1 δηλοί εν φαινυλικόν υπόλοιπον ενδεχομένως υποκατεστημένον δια μιας μεθοξυ-ομάδος ή μίαν αλκυλικήν ομάδα μετά 1-4 ατόμων άνθρακος, και το R2 δηλοί υδρογόνον ή την μεθυλικήν ομάδα, και των εκ τούτων δι' αποσπάσεως ύδατος λαμβανομένων αλκενυλαμινών του τύπου: [*] εις τον οποίον τα R, R1 και R2 έχουν τηνανωτέρω δοθείσαν σημασίαν, ως και των δια προσθήκης οξέων αλάτων αυτών, η μέθοδος δια αύτη διακρίνεται εκ τούτου, ότι: α. Ενα αλκυλεστέρα του β-[1-φαινυλο-προπυλο-(2)-αμινο]-προπιονικού οξέος ή μίαν β-[1-φαινυλο-προπυλο-(2)-αμινο]-αιθυλαρυλο-κετόνηνφέρομεν εις αντίδρασιν μετά οργανομεταλλικών ενώσεων, ή β. ανάγομεν την φαινυλακετόνην παρουσία βασικώς υποκατεστημένων φαινυλοπροπανολών ή μίαν βασικώς υποκατεστημένην φαινυλο-προπανόλην φέρομεν εις αντίδρασιν μετα 1-φαινυλο-2-αλογονο-προπανίων, ή γ. ανάγομεν το Ν-[-1-φαινυλο-προπυλο-(2)-αμίδια του β-υδροξυ-β-φαινυλο-καρβονικού οξέος εις τας αντιστοίχους αμίνας, ενδεχομένως, τας ληφθείσας κεκορεσμένας βασικάς ύδροξυ-ενώσεις υποβάλλομεν εις απόσπασιν ύδατος και/ή τη βοηθεία ανοργάνων ή οργανικών οξέων μετατρέπομεν εις τα αντίστοιχα άλατα. Method for the preparation of essentially substituted propanols of the formula: [*] wherein R denotes a hydrogen atom or the methoxy group, R1 denotes a phenyl moiety optionally substituted by a methoxy group or an alkyl group having 1-4 carbon atoms, and R2 denotes a hydrogen or methyl group, and of water-derived alkenylamines of the following formula: [*] in which R, R1 and R2 have given the above importance, as well as their acid addition salts, the method for it is therefore distinguished that: a. An alkyl ester of β- [1-phenyl-propyl- (2) -amino] -propionic acid or a β- [1-phenyl-propyl- (2) -amino] -ethyrylyl-ketone reacting with organometallic compounds, or b. reduced phenylacetone in the presence of substantially substituted phenylpropanols or a substantially substituted phenylpropanol reacted with 1-phenyl-2-halo-propanes, or c. by reducing the N - [- 1-phenyl-propyl- (2) -amides of β-hydroxy-β-phenylcarboxylic acid to the corresponding amines, optionally, the obtained saturated basic hydroxy compounds are removed and the / with the help of inorganic or organic acids are converted to the corresponding salts.
