Abstract:
Alpha-Hydroxy-epoxides and alpha-alkoxy-epoxides of the formula IV ##STR5## in which the substituents have the following meanings: R.sup.7, R.sup.8, R.sup.9, R.sup.10, R.sup.11 are independently hydrogen, C.sub.1 -C.sub.20 -alkyl, C.sub.3 -C.sub.12 -cycloalkyl, C.sub.4 -C.sub.20 -cycloalkylalkyl, C.sub.1 -C.sub.20 -hydroxy-alkyl, a heterocyclic ring, or an aryl or C.sub.7 -C.sub.20 -arylalkyl group optionally substituted by C.sub.1 -C.sub.8 -alkyl, C.sub.1 -C.sub.8 -alkoxy, halogen, C.sub.1 -C.sub.4 -haloalkyl, C.sub.1 -C.sub.4 -halo-alkoxy, phenyl, phenoxy, halophenyl, halophenoxy, carboxy, C.sub.2 -C.sub.8 -alkoxycarbonyl, or cyano, or R.sup.7 and R.sup.8 or R.sup.7 and R.sup.9 or R.sup.7 and R.sup.10 or R.sup.9 and R.sup.10 or R.sup.10 and R.sup.11 together form a (CH.sub.2).sub.n group in which n is an integer from 1 to 10 and which may be optionally substituted by C.sub.1 -C.sub.8 -alkyl, C.sub.1 -C.sub.8 -alkoxy, and/or halogen, andR.sup.12 is hydrogen, C.sub.1 -C.sub.8 -alkyl, or benzyl,provided that R.sup.10 is not hydrogen, methyl, ethyl, propyl, or cyclohexyl when R.sup.7, R.sup.8, R.sup.9, or R.sup.11 is hydrogen, that R.sup.7 is not methyl when R.sup.8 is methyl or phenyl and R.sup.9, R.sup.10, or R.sup.11 is hydrogen, that R.sup.7 is not methyl when R.sup.8, R.sup.9, R.sup.10, or R.sup.11 is hydrogen and R.sup.12 is ethyl, that R.sup.7 is not phenyl or hexyl when R.sup.8, R.sup.9, R.sup.10, or R.sup.11 is hydrogen, that R.sup.9 is not methyl when R.sup.7, R.sup.8, R.sup.10, or R.sup.11 is hydrogen, that R.sup.10 and R.sup.11 are not methyl when R.sup.7, R.sup.8, or R.sup.9 is hydrogen, and that R.sup.7 and R.sup.10 do not together form an unsubstituted cycloalkyl when R.sup.8, R.sup.9, or R.sup.11 is hydrogen.
