The new amino-alcohols according to the invention are represented by the formula ##SPC1## Wherein: R.sub.1 represents a RS, RSO or RSO.sub.2 group in which R is a linear or branched alkyl group (C.sub.1 -C.sub.10), an acetyl radical or hydrogen; R.sub.2 and R.sub.3, which may be identical or different, represent a halogen atom or an alkyl (C.sub.1 -C.sub.3), amino, alkylamino (C.sub.1 -C.sub.4), acylamino, nitro, carboxy, carbalkoxy, trifluoromethyl, alkoxy (C.sub.1 -C.sub.4) or alkylthio (C.sub.1 -C.sub.4) radical; R.sub.4 represents hydrogen or a linear or branched alkyl radical containing 1 - 4 carbon atoms; R.sub.5 and R.sub.6, which may be identical or different, represent hydrogen, a substituted or not, linear or branched alkyl (C.sub.1 -C.sub.16) radical, a cycloalkyl (C.sub.5 -C.sub.6) radical, an alkynyl (C.sub.3 -C.sub.4) radical, an alkenyl (C.sub.3 -C.sub.4) radical or a heterocycle of the kind piperidine, morpholine, pyridine or pyridimine, R.sub.5 and R.sub.6 can also form with adjacent nitrogen atom a heterocyclic radical, substituted or not; one of said R.sub.2 and R.sub.3 can be a hydrogen atom or can be both a hydrogen atom provided that simultaneously R is a lower alkyl (C.sub.1 -C.sub.3) radical in the group RS, R.sub.4 and R.sub.5 are hydrogen atoms and R.sub.6 is an isopropyl or t-butyl radical or if simultaneously R is a methyl radical in the group RSO.sub.2, R.sub.4 and R.sub.5 are hydrogen atoms and R.sub.6 is an isopropyl radical. When R.sub.5 and R.sub.6 represent an alkyl, the latter can be substituted by amino, alkylamino, hydroxy, alkoxy, phenoxy, substituted phenoxy, phenyl, substituted phenyl radical or a heterocycle such as piperidino or morpholino.
根据发明,新的氨基醇可由以下式表示:其中:R.sub.1代表RS、RSO或RSO.sub.2基团,其中R为直链或支链烷基(C.sub.1 -C.sub.10)、乙酰基团或氢原子;R.sub.2和R.sub.3,可能相同也可能不同,代表卤素原子或烷基(C.sub.1 -C.sub.3)、氨基、烷基氨基(C.sub.1 -C.sub.4)、酰胺基、硝基、羧基、羧酸烷氧基、三氟甲基、烷氧基(C.sub.1 -C.sub.4)或烷硫基(C.sub.1 -C.sub.4)基团;R.sub.4代表氢原子或含有1-4个碳原子的直链或支链烷基基团;R.sub.5和R.sub.6,可能相同也可能不同,代表氢原子、取代或非取代的直链或支链烷基(C.sub.1 -C.sub.16)基团、环烷基(C.sub.5 -C.sub.6)基团、炔基(C.sub.3 -C.sub.4)基团、烯基(C.sub.3 -C.sub.4)基团或哌啶、吗啉、吡啶或吡啶咪唑等异环的基团,R.sub.5和R.sub.6也可以与相邻的氮原子形成取代或非取代的杂环基团;其中R.sub.2和R.sub.3中的一个可以是氢原子,或者同时R为RS中的较低烷基(C.sub.1 -C.sub.3)基团时,R.sub.4和R.sub.5为氢原子,R.sub.6为异丙基或叔丁基基团;或者同时R为RSO.sub.2中的甲基基团时,R.sub.4和R.sub.5为氢原子,R.sub.6为异丙基基团。当R.sub.5和R.sub.6代表烷基时,后者可以被氨基、烷基氨基、羟基、烷氧基、苯氧基、取代苯氧基、苯基、取代苯基基团或哌啶啉或吗啉等异环所取代。
