| titleOfInvention | Process for the preparation of 1-hydroxymethyl oxiranes z-substituted in position 2 |
| abstract | Process for the preparation of 1-hydroxy-methyl-oxiranes of the general formula I and ent-I which are Z-substituted in the 2-position, in which the substituents A, B independently of one another C₁-C₄-alkyl, phenyl, naphthyl, diphenyl or phenyl substituted by one to three radicals from the group halogen, C₁-C₄-alkyl, C₁-C₄-alkoxy, C₁-C₄-haloalkyl, nitro or phenoxy mean by ketones of the general formula II in which A and B have the meanings given above and X represents a group which can be eliminated under the reaction conditions, is reacted with trimethyl sulfonium methyl sulfate and a suitable base or with dimethyloxosulfonium methylide, and new ketones of the general formula II ' in which the substituents A ′ phenyl or 4-fluorophenyl, B ′ 2-fluorophenyl, 2-chlorophenyl, 2-bromophenyl or 2-trifluoromethylphenyl and X ′ hydroxy or a leaving group mean, with the proviso that B 'is not 2-chlorophenyl when A' is phenyl. |
