- R.sup.2 C.sub.1 -C.sub.20 -alkylamino, and
- R.sup.3 is formyl, unbranched or branched (C.sub.1 -C.sub.20 -alkyl)-carbonyl which is unsubstituted or substituted in the alkyl moiety by one or more radicals from the series comprising hydroxyl, halogen, C.sub.1 -C.sub.4 -alkoxy, C.sub.1 -C.sub.4 -alkylthio, and phenyl which can be substituted by up to three radicals from the group comprising C.sub.1 -C.sub.12 -alkyl, C.sub.1 -C.sub.12 -alkoxy, halogen, nitro and CF.sub.3, or R.sup.3 is benzoyl or benzoyl which is substituted by 1 to 3 radicals from the group comprising C.sub.1 -C.sub.12 -alkyl, C.sub.1 -C.sub.12 -alkoxy, halogen, nitro and CF.sub.3, or
- b)
- R.sup.1 is as defined for a),
- R.sup.2 is C.sub.1 -C.sub.20)-alkylamino, and
- R.sup.3 is as defined for a) or is another protective group customary in the case of amino groups.
- 2. A compound as claimed in claim 1, wherein
- a)
- R.sup.1 is unbranched or branched C.sub.1 -C.sub.6 -alkyl, or is cyclohexyl,
- R.sup.3 is (C.sub.1 -C.sub.4 -alkyl)carbonyl or (C.sub.1 -C.sub.4 -alkyl)carbonyl which is substituted by phenyl or by phenyl which is monosubstituted to trisubstituted and whose 1 to 3 substituents are selected from amongst C.sub.1 -C.sub.4 -alkyl, C.sub.1 -C.sub.4 -alkoxy and halogen, or R.sup.3 is benzoyl, or
- b)
- R.sup.1 is unbranched or branched C.sub.1 -C.sub.6 -alkyl, or is cyclohexyl,
- R.sup.3 is as defined for a), or is unbranched or branched (C.sub.1 -C.sub.4 -alkoxy)carbonyl, preferably tert.-butyloxycarbonyl, or is benzyloxycarbonyl which can additionally be substituted in the phenyl ring by up to three radicals from the group comprising C.sub.1 -C.sub.4 -alkyl, C.sub.1 -C.sub.4 -alkoxy and halogen.
- 3. A compound as claimed in claim 2, wherein
- a)
- R.sup.1 is methyl, ethyl, propyl, butyl, pentyl, hexyl, or cyclohexyl,
- R.sup.3 is acetyl or phenacetyl, or
- b)
- R.sup.1 is as defined for a),
- R.sup.3 is as defined for a), or is tert.-butyloxycarbonyl or benzyloxycarbonyl.
- 4. A compound as claimed in claim 3, wherein R.sup.1 is cyclohexyl and R.sup.3 is phenacetyl.
- 5. A compound of the general formula ##STR6## wherein R.sup.1 is unbranched or branched (C.sub.1 -C.sub.6)-alkyl,
- R.sup.2 is (C.sub.1 -C.sub.20 )-alkylamino,
- R.sup.3 is formyl, acetyl, chloroacetyl or propionyl.
