-
Paragraph 0593; 0594; 0595, (2014/08/07)
The invention relates to novel compounds of the formula (I) in which W, X, Y, Z, A, B and G have the meanings given above, to a plurality of processes and intermediates for their preparation, and to their use as pesticides and/or herbicides. The invention also provides selective herbicidal compositions comprising, firstly, geminally alkoxy/alkylspirocyclically substituted tetramic acid derivatives and, secondly, a crop plant compatibility-improving compound. The invention furthermore relates to the boosting of the action of crop protection compositions comprising compounds of the formula (I) through the addition of ammonium salts or phosphonium salts and optionally penetrants.

Studies toward the synthesis of menogaril: Synthesis of a-ring precursors and their conversion to the tetracyclic core via the benzannulation reaction

A model study for the synthesis of menogaril is reported which involves the benzannulation reaction of a Fischer carbene complex with an alkyne that contains the A-ring of the tetracyclic core of menogaril. The synthesis of methoxy and benzyloxy derivatives of this alkyne are reported as well as the reaction of the methoxy derivative with an o-methoxyphenyl carbene complex to generate a tricyclic naphthol containing three of the four rings of menogaril core. Completion of the model study and the synthesis of the tetracyclic anthracyclinone core of menogaril was accomplished by an intramolecular Friedel-Crafts cyclization.
