Definitions
- the present invention relates to bisamide zinc bases, their preparation and the use of the zinc bases.
- the present invention relates to bisamide zinc bases which can be used to prepare aryl and heteroaryl metal compounds.
- the preparation of aryl and heteroaryl metal compounds can be effected either by a halogen-metal-exchange reaction (eg, bromine-lithium exchange 1 ), insertion of elemental metal into a carbon-halogen bond (eg, zinc insertion into a carbon-iodine bond 2 ), or metalation (deprotonation with Help strong bases 3 ) take place.
- a halogen-metal-exchange reaction eg, bromine-lithium exchange 1
- elemental metal into a carbon-halogen bond eg, zinc insertion into a carbon-iodine bond 2
- metalation deprotonation with Help strong bases 3
- aryl or heteroaryl iodo compounds are generally expensive and usually not long lasting.
- Another disadvantage of exchange reactions and insertions, especially on a larger reaction scale, is the formation of metal salts, some of which must be disposed of separately. Therefore, it is desirable to have an alternative method of functionalizing aromatic and heteroaromatic compounds based on C-H activation.
- organolithium compounds are the most reactive reagents. 5
- Organomagnesium compounds such as TMPMgCl-LiCl have a higher stability, but here too the tolerance to sensitive functional groups such as aldehydes and nitro groups is limited. 7
- Another reagent for the metallation of aromatics is TMPZn ⁇ Bu 2 Li, whose high activity is based on a Zinkatspezies. 8
- Another zinc base is the neutral Zn (TMP) 2.

- the zinc-containing salt which is also referred to as zinc salt
- a solvent Possible solvents are the same as the solvents mentioned above for the magnesium amide.
- the zinc salt is dried and charged without solvent and then the magnesium amide is added in a solvent. As a result, the total amount of solvent can be kept low and the zinc salt can be easily dried. In addition, side reactions are reduced.

If the concentration is too low, the dilution in the reaction mixture can be so great that z. If the concentration is too high, it is possible that the zinc amide base precipitates and must be redissolved with additional solvent. Precipitation of the zinc amide base is not detrimental to the base itself, but controlled aliquot measurement is difficult due to the unknown amount of precipitated amide.

- An advantage of using the zinc amide bases according to the invention is that they can be added in a low concentration.
- two protons can be abstracted with a zinc amide base. These may be present within a substrate, or preferably two protons may be abstracted from two substrates. Therefore, it is possible to add the zinc amide base of the present invention in an amount of about 0.5-0.6 equivalent to the substrate, if only one proton in a substrate is to be abstracted. Based on the number of protons abstracted to the zinc amide base may be added in an amount of about 0.5 to 0 ⁇ 6 equivalents. With lower acidity of the protons to be abstracted, an increased addition amount of zinc amide base may be necessary.
- the zinc amide base may preferably be added in an amount of 1.0-1.1 equivalents to the substrate.
- alkyl is meant here a saturated hydrocarbon radical which may be branched or unbranched, ie straight-chain.
- the alkyl comprises 1-20 carbon atoms and forms a C] -C 2 o-alkyl radical.
- radicals having 1-10 carbon atoms ie C 1 -C 10 -alkyl radicals, more preferably radicals having 1 to 6 carbon atoms, ie C 1 -C 6 -alkyl radicals.
- radicals examples include methyl, ethyl, n-propyl, isopropyl, n-butyl, sec-butyl, tert-butyl, n-pentyl and n-hexyl, without, however, being restricted to these examples.
- alkenyl should be understood as meaning an unsaturated hydrocarbon radical having at least one carbon-carbon double bond.
- Preferred radicals include C 2 -C 2 o-alkenyl radicals. More preferred are C 2 -C 10 -alkenyl radicals and most preferably C 3 -C 6 -alkenyl radicals.
- a particularly preferred radical is the allyl radical.

- Preferred alkynyl radicals include C 2 -C 20 alkmyl radicals. More preferred are C 2 -Cio-alkynyl radicals and most preferably C 3 -C 6 -alkenyl radicals.
- Silyl is understood in this application to mean a substituted by alkyl, alkenyl or alkynyl silicon atom.
- a silyl radical can consequently be replaced by the general one Formula -Si (R S! R S2 R S3 ) where R s ⁇ R S2 and R S3 are each independently selected from alkyl, alkenyl, alkynyl, aryl or heteroaryl, all radicals being as defined above.
- Preferred silyl radicals include trimethylsilyl, triethylsilyl, triisopropylsilyl, t-butyldimethylsilyl and triphenylsilyl.

- Alcohols and alcoholates including hydroxyl groups
- the substituents may be bonded to the radicals via a carbon atom, an oxygen atom, a nitrogen atom, a sulfur atom or a phosphorus atom.
- heteroatoms e.g. in heteroaromatics, B, N, O, S and P are preferably used.
- the content of the Magesiumamidbasen and the Zinkbisamidbasen was determined using benzoic acid as a proton source and 4 (phenylazo) diphenylamine as an indicator.
- An example of a zinc amide base according to the invention is the neutral base Zn (TMP) 2 -2LiCl-2MgCl 2 (1). It allows the metalation of arenes and heteroarenes under mild conditions. Here, a variety of functional groups, such as ester, cyano, nitro and aldehyde function as well as chlorine or bromine, can be tolerated. Zn (TMP) 2 4 2LiCl-2MgCl 2 can easily be prepared in a two-step synthesis according to Scheme 1.
- Scheme 1 Preparation of Zn (TMP) 2 -2LiCl-2MgCl 2 (1). Starting from the analogous magnesium amides DAMgCl-LiCl and HMDSMgCl-LiCl, it is also possible to visualize Zn (DA) 2 -2LiCl-2MgCl 2 (2) and Zn (HMDS) 2 -2LiCl-2MgCl 2 (3) (Scheme 2). Where DA is diisopropylamine and HMDS is hexamethyldisilazane. However, these bases have less activity than 1.
- the presence of a lithium salt in the zinc amide base increases the effectiveness of the zinc amide base.
- the Mg salt formed in the preparation of the neutral zinc base also leads to an increase in reactivity and to improved solubility of the metallated species.
- diaryl and DiheteroarylzinkENSen can be implemented in a variety of ways with electrophiles.
- the diaryl and DiheteroarylzinkENS can be transmetallated eg on copper to perform allylations or acetylations (see Scheme 3).
- the presence of the zinc amide base can be shown on another system (see Scheme 6).
- 2-phenyl [l, 3,4] oxadiazole can be deprotonated in a short time.
- the organomagnesium compound decomposes very rapidly to the indicated products at room temperature.
- the organozinc compound is stable at room temperature and can be further reacted with electrophiles.
- both the presence of Mg and Li in the zinc amide base is important. If one of these metals is missing, the reactivity is greatly reduced or no reaction takes place. However, it is also important to have a bisamide base. If only one monoamide base is present, as in entry 3, no reaction can be observed.
- a further increase in the reactivity of the zinc amide bases can be achieved by the use of microwave radiation.
- the reaction time can be significantly shortened by the use of microwave radiation.
- One embodiment of the use of the compounds of the formula I is a reaction with an electrophile, wherein first a CH-acidic substrate is deprotected with a compound of the formula I and then the deprotonated substrate is reacted with an electrophile.
- the deprotonation of the CH-acidic substrate is carried out under microwave irradiation.
- Microwave irradiation with an energy in the range of 1 to 500 W, preferably in the range of 20 to 300 W, more preferably in the range of 40 to 200 W, and most preferably in the range of 80 to 150 W is particularly advantageously used.
- microwave-accelerated metallation is an extremely useful tool for the functionalization, in particular of aromatics and heteroaromatics, since even inert substrates can be reacted efficiently and quickly.
- this approach has shown a major step in combining high reactivity with selectivity and tolerance to sensitive functional groups.
- ZnCl 2 (21.0 mmol, 2.86 g) is dried in a 100 mL Schlenk flask with stirring in an oil pump vacuum at 150 ° C. for 5 h. After cooling, TMPMgCl-LiCl (40.0 mmol, 1.11 M, 36.0 mL) dissolved in tetrahydrofuran (THF) is slowly added at room temperature and stirred at room temperature for 15 h. Any possible precipitation of Zn (TMP) 2 -2LiCl-2MgCl 2 can be redissolved by adding dry THF.
- THF tetrahydrofuran
- the aqueous phase was extracted with ethyl acetate (5 x 10 mL), dried over MgSO 4 and concentrated under reduced pressure.
- the crude product was purified by filter column chromatography (silica gel; CH 2 Cl 2 ); 5 h (133 mg, 81%) were obtained as a yellow, crystalline solid.
