Definitions
- the present invention relates to a new process for the preparation of 2- (phenylimino) -3-alkyl-1,3-thiazolidin-4-ones of the general formula (I).
- a simple and effective method consists in reacting an appropriately substituted aniline of the general formula (IV) with an isothiocyanate of the general formula (V) (WO2014 / 202510). Conversely, it is also possible to react an aryl isothiocyanate of the general formula (VI) with an amine of the general formula (VII) and in this way to obtain the N, N‘-disubstituted thiourea of the general formula (II) (JP2011 / 042611).
- a process that has become known for the preparation of 2- (phenylimino) -3-alkyl-1,3-thiazolidin-4-ones of the general formula (I) is accordingly characterized in that, in a first step, an aniline of the general formula (IV ) with an isothiocyanate of the general formula (V), or an aryl isothiocyanate of the general formula (VI) with an amine of the general formula (VII) and then the N, N'-disubstituted thiourea of the general formula (II) thus formed is isolated , for example by filtration.
- the N, N'-disubstituted thiourea of the general formula (II) is then converted into 2- (phenylimino) -3-alkyl-1,3 with an acetic acid derivative of the general formula (III) in the presence of a base -thiazolidin-4-one of the general formula (I) implemented.
- isothiocyanates namely either the alkyl isothiocyanate of the general formula (V) or the aryl isothiocyanate of the general formula (VI).
- Isothiocyanates can often only be produced with complex methods using dangerous chemicals.
- isothiocyanates of the general formulas (V) and (VI) can be prepared by reacting an amine of the general formula (VII) or an aniline of the general formula (IV) with thiophosgene (Rapid Communications in Mass Spectrometry 8 (1994) 737).
- thiophosgene is very disadvantageous here.
- Thiophosgene is highly toxic; is very corrosive; has a foul odor; and is generally bad and only too high Costs available.
- Another known method for preparing isothiocyanates of the general formulas (V) and (VI) consists in adding an amine of the general formula (VII) or an aniline of the general formula (IV) in the presence of a base such as, for example, triethylamine with carbon disulfide to implement the dithiocarbamates of the general formula (VIII) and then to react them with reagents such as chloroformic acid esters (/. Org. Chem. 29 (1964) 3098), tosyl chloride (WO2012 / 129338), phosgene (Chem.
- 2- (phenylimino) -3-alkyl-1,3-thiazolidin-4-ones of the general formula (I) can be prepared by adding a 2- (phenylimino) -3H-1,3-thiazolidine -4-one of the general formula (VIII) reacts with an alkylating agent of the general formula (IX).
- the present invention accordingly provides a new process (B) for the preparation of 2- (phenylimino) -3-alkyl-1,3-thiazolidin-4-ones of the general formula (I) in which Y 1 and Y 2 independently represent fluorine, chlorine or hydrogen,
- R 1 and R 2 independently represent hydrogen, (Ci-Ci2) alkyl, (Ci-Ci2) haloalkyl, cyano, halogen or nitro, and
- R 3 represents optionally substituted (Ce-Cio) aryl, (Ci-Ci2) alkyl or (Ci-Ci2) haloalkyl, the substituents being selected from halogen, (Ci-C 6 ) alkyl, (C3-Cio) cycloalkyl, Cyano, nitro, hydroxy, (Ci-C 6 ) alkoxy, (Ci-C 6 ) haloalkyl and (Ci-C 6 ) haloalkoxy, in particular from fluorine, chlorine, (Ci-C3) alkyl, (C3-C6) cycloalkyl, Cyclopropyl, cyano, (Ci-C3) alkoxy, (Ci-C3) haloalkyl and (Ci-C3) haloalkoxy, which is characterized in that a 2- (phenylimino) -3H-l, 3-thiazolidine-4- on the general formula (VIII): in which Y
- R 3 has the meaning given above and Z stands for iodine, bromine, chlorine, 0S0 2 Me, 0S0 2 Ph, 0S0 2 (4-Me-Ph), 0S0 2 CF 3 , 0S0 2 C 2 F 5 , 0S0 2 C 3 F 7 , OSCEC4F9, 0S0 2 CF 2 C00Me, 0S0 2 CF 2 C00Et, 0S0 2 CF 2 C00nPr, 0S0 2 CF 2 C00iPr or
- the 2- (phenylimino) -3-alkyl-1,3-thiazolidin-4-ones of the general formula (I) can be prepared with good yields and in high purity using the process according to the invention.
- the compounds of the formula (I) can exist as E or Z isomers or as a mixture of these isomers. This is illustrated by the crossed double bond in formula (I).
- the E isomer is present in each case.
- the Z isomer is present in each case.
- the Z isomer or a mixture of E and Z isomer is present in which the proportion of the Z isomer is greater than 50% and increasingly preferably greater than 60%, 65%, 70% , 75%, 80%, 85%, 90%, 95% based on the total amount of E and Z isomers in the mixture.
- the starting material of the general formula (VIII) also consists of a tautomeric form of the general formula (VIII ') in which Y 1 , Y 2 , R 1 and R 2 have the meanings given above, can react, the products of the general formula (X) (2 - [ ⁇ 2-phenyl ⁇ (alkyl) amino] -l, 3-thiazol-4 (5H)) isomeric to the compounds of the formula (I) can also -one) in which Y 1 , Y 2 , R 1 , R 2 and R 3 have the meanings given above, are obtained.
- the process according to the invention is also characterized in that the compounds of the general formula (I) are obtained in high selectivity, i.e. in significantly higher proportions than the compounds of the general formula (X).
- Y 1 and Y 2 independently of one another represent fluorine, chlorine or hydrogen
- R 1 and R 2 independently of one another for fluorine, chlorine, (Ci-C3) alkyl or hydrogen, R 3 for (Ci-Ce) alkyl or (Ci-C 6 ) haloalkyl, and
- Y 1 and Y 2 independently of one another for fluorine or hydrogen, R 1 and R 2 independently of one another for fluorine, chlorine, hydrogen or methyl,
- R 1 and R 2 independently of one another represent fluorine, hydrogen or methyl
- R 3 for (Ci-C 6 ) fluoroalkyl
- the present application also relates to compounds of the general formula (VIII) in which Y 1 , Y 2 , R 1 and R 2 have the meanings given above.
- Y 1 and Y 2 independently of one another represent fluorine, chlorine or hydrogen
- R 1 and R 2 independently of one another represent fluorine, chlorine (Ci-C 3 ) alkyl or hydrogen. Accordingly, they are particularly preferred
- Y 1 and Y 2 independently of one another represent fluorine or hydrogen
- R 1 and R 2 independently of one another represent fluorine, chlorine, hydrogen or methyl.
- Y 1 and Y 2 are very particularly preferably fluorine, and
- R 1 and R 2 independently of one another represent fluorine, hydrogen or methyl.
- Y 1 and Y 2 stand for fluorine
- R 1 for methyl and R 2 for fluorine.
