Definitions
- the present invention relates to a novel process for preparing known spirocyclic tetronic acid derivatives.
- Spirocyclic tetronic acid derivatives as well as their possible uses as insecticidal or acaricidal agents are known inter alia from EP-A-0 528 156.
- the required structure of the spirocyclic tetronic acid structure is carried out via esters of the general formula (I)
- X is C 1 -C 6 -alkyl, halogen, C 1 -C 6 -alkoxy or C 1 -C 3 -
- Haloalkyl Y represents hydrogen, C:. -C 6 alkyl, halogen, C 1 -C 6 -alkoxy or C 1 -
- Z stands for C 1 -C 6 -alkyl, halogen, C 1 -C 6 -alkoxy and n stands for a number 0-3 R 1 for alkyl and A and B together with the carbon atom to which they are bonded for a saturated or unsaturated, optionally substituted carbocycle or heterocycle
- A, B, X, Y, Z and n are as defined above and G is hydrogen, a metal equivalent, an optionally substituted ammonium or a group -CO-R 4 in which R 4 is alkyl.
- A, B, X, Y, Z and n are as defined above and R 5 is alkyl.
- the spirocyclic tetronic acids initially form in the form of their anionic salts under the basic reaction conditions, but can also be obtained by subsequent acidification into their free acids or by addition of an acylating agent of the general formula (VI)
- R 4 has the abovementioned meaning
- LG stands for chlorine or any other leaving group
- Suitable bases are all customary proton acceptors or combinations thereof, for example alkali metal or alkaline earth metal oxides, hydroxides, amides, hydrides or alkoxides, alkali metals or tertiary amine bases, for example 1,8-diazabicyclo [5.4.0 ] undec-7-ene (DBU), 1, 5-diazabicyclo [4.3.0] non-2-ene (DBN) or 1, 4-diazabicyclo [2.2.2] octane (DABCO).
- DBU 1,8-diazabicyclo [5.4.0 ] undec-7-ene
- DBN 1,5-diazabicyclo [4.3.0] non-2-ene
- DABCO 4-diazabicyclo [2.2.2] octane
- diluents it is possible to use alcohols and all solvents which are inert under the reaction conditions or combinations thereof, preferably polar solvents such as, for example, 1,2-dimethoxyethane (glyme), 1,4-dioxane or tetrahydrofuran (THF), N-methylpyrrolidone (NMP) or N , N-dimethylformamide (DMF), dimethylsulfoxide (DMSO), sulfolane.
- polar solvents such as, for example, 1,2-dimethoxyethane (glyme), 1,4-dioxane or tetrahydrofuran (THF), N-methylpyrrolidone (NMP) or N , N-dimethylformamide (DMF), dimethylsulfoxide (DMSO), sulfolane.
- phase transfer catalysts eg: Triethylbenzylammonium chloride or tetrabutylammonium bromide
- the reaction can be carried out in the range of 0-200 0 C, preferably at 40-120 0 C.
- reaction is carried out at atmospheric pressure, but can also be carried out in vacuo or under pressure. If, after the reaction, an acylation of the tetronic acid salt is to take place, it is advisable to remove the alcohols formed during the reaction by means of distillation under reduced pressure.
- reaction components of the formulas (II) and (III) are generally used in approximately equimolar amounts. However, it is also possible to use one or the other component in a larger excess (up to 5 mol).
- the base used is generally used in approximately equimolar amounts or in a slight excess, but can also be used in far greater excess (up to 20 mol).
- the starting materials of the general formulas (II) and (III) are known and mostly commercially available compounds or can be prepared by generally customary processes of organic chemistry.
