ABSTRACT:
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.
