    • Organic materials which contain from 0.001 to 10% by weight of an aminoreductone I ##STR1## where R.sup.1, R.sup.2 and R.sup.3 are H, methyl or ethyl and R.sup.4 is the radical of a naturally occurring .alpha.- or .beta.-aminoacid or of a C.sub.1 -C.sub.10 -alkyl ester thereof or, in the case of an .alpha.-aminoacid, a lactone having a 2--OH group in the cyclohexenone ring, or R.sup.4 is C.sub.1 -C.sub.20 -alkyl which is unsubstituted or substituted by --OH, C.sub.1 -C.sub.4 -alkoxy or C.sub.1 -C.sub.4 -acyloxy, or is --(CH.sub.2 --CH.sub.2 --O).sub.n H, which may be etherified with a C.sub.1 -C.sub.4 -alkanol or esterified with a C.sub.1 -C.sub.4 -fatty acid, and where n is from 2 to 10, or a mineral salt thereof.Novel compounds Ia differ from I in having the radical R.sup.4a, where R.sup.4a is R.sup.4 with the exception of methyl. Compounds I are prepared by reacting the corresponding 2,3-dihydroxycyclohex-2-en-1-one with an amine HN(R.sup.3)R.sup.4 or a mineral acid salt thereof.
    • 含有0.001至10重量%的氨基还原酮I的有机材料,其中R 1,R 2和R 3是H,甲基或乙基,R 4是天然存在的α-或β-氨基酸或C1 -C 10 - 烷基酯,或在α-氨基酸的情况下,在环己烯酮环中具有2-OH基团的内酯,或R4是未被取代或被-OH取代的C1-C20烷基,C1-C4 - 烷氧基或C 1 -C 4 - 酰氧基,或是 - (CH 2 -CH 2 -O)n H,其可以用C 1 -C 4烷醇醚化或用C 1 -C 4脂肪酸酯化,并且其中n为2至 10或其矿物盐。 新颖的化合物Ia与具有自由基R4a的不同之处在于,R4a除了甲基以外是R4a。 化合物I通过使相应的2,3-二羟基环己-2-烯-1-酮与胺HN(R3)R4或其无机酸盐反应来制备。
