Abstract

The present invention relates to novel intermediates used in the preparation of substituted spirocyclic ketoenols of the formula (I) in which W, X, Y, Z, A, B, D and G are as defined in the disclosure.

Claims (16)

1. A compound of formula (XVII),

in which

A represents an optionally substituted alkanediyl group; and

B represents optionally halogen substituted alkenyl, alkoxy, or alkoxyalkyloxy, or represents substituted phenyl; or represents cycloalkyl that is optionally substituted and/or in which the cycloalkyl ring is optionally interrupted by one or more heteroatoms and/or C═O.

2. A compound according to claim 1 in which

A represents an optionally C 1 -C 4 -alkyl-substituted C 1 -C 4 -alkanediyl group; and

B represents optionally halogen-substituted C 2 -C 8 -alkenyl, C 1 -C 6 -alkoxy, or C 1 -C 6 -alkoxy-C 1 -C 4 -alkyloxy; represents halogen-, C 1 -C 6 -alkyl-, C 1 -C 6 -alkoxy-, C 1 -C 4 -haloalkyl-, C 1 -C 4 -haloalkoxy-, cyano-, or nitro-substituted phenyl; or represents optionally halogen-, C 1 -C 4 -alkyl-, C 1 -C 4 -alkoxy- or C 1 -C 2 -haloalkyl-substituted C 3 -C 8 -cycloalkyl in which one or two methylene groups of the cycloalkyl ring that are not directly adjacent are optionally replaced by oxygen or three methylene groups of the cycloalkyl ring are optionally replaced by a group —O—CO—O—.

3. A compound of formula (XIV)

in which

A represents an optionally substituted alkanediyl group;

B represents optionally halogen substituted alkenyl, alkoxy, or alkoxyalkyloxy, or represents substituted phenyl; or represents cycloalkyl that is optionally substituted and/or in which the cycloalkyl ring is optionally interrupted by one or more heteroatoms and/or C═O, and

R 8 represents alkyl.

4. A compound according to claim 3 in which

A represents an optionally C 1 -C 4 -alkyl-substituted C 1 -C 4 -alkanediyl group;

B represents optionally halogen-substituted C 2 -C 8 -alkenyl, C 1 -C 6 -alkoxy, or C 1 -C 6 -alkoxy-C 1 -C 4 -alkyloxy; represents halogen-, C 1 -C 6 -alkyl-, C 1 -C 6 -alkoxy-, C 1 -C 4 -haloalkyl-, C 1 -C 4 -haloalkoxy-, cyano-, or nitro-substituted phenyl; or represents optionally halogen-, C 1 -C 4 -alkyl-, C 1 -C 4 -alkoxy- or C 1 -C 2 -haloalkyl-substituted C 3 -C 8 -cycloalkyl in which one or two methylene groups of the cycloalkyl ring that are not directly adjacent are optionally replaced by oxygen or three methylene groups of the cycloalkyl ring are optionally replaced by a group —O—CO—O—, and

R 8 represents C 1 -C 6 -alkyl.
