Definitions
- the present invention relates to a process for the preparation of acetylene alcohols by monoethynylation of a ketone by reacting an alkyl halide with lithium.
- a monolithium acetylide complex is reacted with the corresponding carbonyl compound in an inert organic solvent (CH 642 936).
- the active lithium acetylide ammonia complex is prepared by evaporating ammonia from a lithium acetylide ammonia solution at -30 to -20 ° C and replacing it with an organic solvent.
- the reaction of lithium amide with acetylene in an inert organic solvent is mentioned.
- No. 2,472,310 describes a method for the ethynylation of rapidly aldolizing ketones, such as, for example, ⁇ -ionone, under basic conditions.
- the lithium acetylene-ammonia complex required for this is shown by introducing acetylene into liquid ammonia at -40 ° C. and simultaneously adding lithium (OA Shavrygina, DV Nazarova, SM Makin, Zh. Org. Khim. 1966, 2, 1566-1568).
- a disadvantage of the processes mentioned is the low selectivity of the lithium acetylide formation, since the lithium acetylide can be present as mono- or dilithium acetylide or as a mixture of the two components.
- Another disadvantage is the low temperature required to keep the ammonia liquid and the solvent exchange after lithium acetylide formation.
- US 2,425,201 discloses a process for the production of ⁇ , ⁇ -unsaturated ketones using calcium acetylidene. The ethynylation takes place at temperatures from -70 to -40 ° C.
- DE 10 81 883 describes a process for the preparation of ethyl ionol by reacting sodium acetylide with ⁇ -ionone in an organic solvent. To increase the acetylene concentration tion in the reaction mixture, acetylene is used under pressure. Compared to the unpressurized procedure, ethynyl ionol is obtained in an improved yield.
- the preparation of lithium acetylide is based on the reaction of lithium with naphthalene and acetylene, a naphthalene radical anion being first formed by electron transfer, which then acts as a base and forms the lithium acetylide with acetylene.
- the reaction with ⁇ -ionone then gives the desired ehinyl ionol in 90% yield (K. Suga, S. Watenabe, T. Suzuki, Can. J. Chem. 1968, 46, 3041-3045).
- the use of semi-stoichiometric amounts of naphthalene based on ⁇ -ionone is not advantageous here.
- a catalytic process for the preparation of alkyl lithium compounds is also known.
- Lithium forms a radical anion in the presence of 4,4-di-tert-butylphenyl as a catalyst by simple electron transfer, which forms the corresponding alkyl lithium species by reaction with alkyl halides (PK Freeman, L. L: Hutchinson, Tetrahedron Letters, 1976, 22, 1849-1852; PK Freeman, LL: Hutchinson, J. Org. Chem. 1983, 48, 4705-4713).
- naphthalene can also be used as a catalyst.
- the alkyl lithium compound obtained in the reaction is preferably used for the alkylation of various electrophiles (M. Yus, D. Ramon, J. Chem. Soc., Chem. Comm. 1991, 398-400; TR van den Ancker, MJ Hdgson , J. Chem. Soc, Perkin Trans. 1, 1999, 2869-2870).
- the object of the invention was to develop an economical process for the production of acetylene alcohols which does not have the disadvantages described in the prior art. Surprisingly, the object was achieved according to the invention by a one-pot process for the preparation of acetylene alcohols of the general formula I.
- R 1 , R 2 can each independently be the same or different and are hydrogen, a saturated or a mono- or polyunsaturated C 1 -C 3 o-alkyl, aryl, cycloalkylalkyl or cycloalkyl radical, which can optionally be substituted or a group of the general formula (II) can mean
- R 3 , R 4 can each independently be the same or different and are hydrogen or a saturated or a mono- or polyunsaturated C ⁇ -C 3 o-alkyl, aryl, cycloalkylalkyl or cycloalkyl radical, which can be optionally substituted and the dashed line Line can mean an additional double bond
- the reaction of lithium with alkyl halide preferably takes place in the presence of catalytic amounts of naphthalene or 4,4'-di-tert-butylbiphenyl.
- Tetrahydrofuran can be used as a solvent.
- a C 1 -C 4 alkyl radical means a methyl, ethyl, propyl, i-propyl, butyl or t-butyl radical.
- a mono- or polyunsaturated straight-chain or branched C 1 -C 30 -alkyl radical means, for example, unless otherwise stated, a methyl, ethyl, propyl, isopropyl, n-butyl, i-butyl, t-butyl, pentyl, hexyl, heptenyl , Octyl, nonyl, decyl, 1-propenyl, 2-propenyl, 2-methyl-2-propenyl, 1-pentenyl, 1-methyl-2-pentenyl, isopropenyl, 1-butenyl, hexenyl , Heptenyl, octenyl, nonenyl, or a decenyl radical or the radicals corresponding to the compounds listed below.
- Cycloalkyl stands for a 3-7-membered saturated or a mono- or polyunsaturated 3-7-membered ring in which a CH group can be replaced by 0 or NH, as u. a. the cyclopropyl, cyclobutyl, cyclopentyl, cyclohexyl or the cycloheptyl ring, preferably the cyclopentyl or the cyclohexyl ring.
- An aryl radical means a benzyl, phenyl or naphthyl radical.
- C 1 -C 4 -alkyl can be methyl, ethyl, propyl, i-propyl, butyl, t-butyl, fluorine, chlorine, bromine, iodine, nitro or amino radicals.
- ketones can be used, for example, for ethynylation:
- 6-methylheptanone hexahydrofarnesylacetone, diethyl ketone, methyl ethyl ketone, cyclohexanone, methyl t-butyl ketone, pseudo-ionone, methyl hexenone, H-geranylacetone, preferably acetone, methyl vinyl ketone or ⁇ -ionone.
- an alkyl halide for example 1-chlorobutane at temperatures from -20 to -10 ° C.
- acetylene gas is introduced to produce lithium acetylide.
- the ketone is added at 0 to 10 ° C., preferably at 0 ° C. Surprisingly, there is no disproportionation of the lithium acetylide into dilithium acetylide and acetylene.
- Tetrahydrofuran can be used as the solvent.
- the process according to the invention enables acetylene alcohols to be prepared in good to very good yields, for example starting from the ketones acetone, ⁇ -ionone or methyl vinyl ketone.
- the ethynylation products of ß-ionone and methyl vinyl ketone are precursors of vitamin A and astaxanthin synthesis.
- Trimethylsilyl chloride is used to prepare trimethylsilacetylene.
- Trimethylsilyacetylene is used to prepare endiins that are active as anti-tumor reagents.
- the reaction takes place in two 250 ml cervical vessels under argon.
- 2.4 g (0.34 mol) of lithium wire is cut into small pieces and suspended together with 5.4 g (20 mol) of the catalyst in 200 ml of tetrahydrofuran at -15 ° C.
- 14.8 g (0.16 mol) of 1-chlorobutane in 20 ml of tetrahydrofuran are added via a dropping funnel within two hours and then stirred for a further two hours.
- the lithium is separated off by transferring the supernatant solution into a second ml HWS vessel, into which acetylene is then introduced at -15 ° C.
