| titleOfInvention | PRODUCTION OF N-SUBSTITUTED N-OXIDES OF SULFOXYMINPYRIDINE |
| abstract | 1. A method of producing an N-oxidized sulfoximine compound of the formula (I) wherein X is NO, CN, COOR or CONH; L is a single bond or R, S and L, taken together, are a 4-, 5- or 6-membered ring; R is (CC) alkyl; R and R individually represent a hydrogen atom, methyl, ethyl, fluorine atom, chlorine atom or bromine atom; n is an integer from 0 to 3; Y is (CC) halogenated, F, Cl, Br or I; and R denotes (CC) alkyl; comprising oxidizing a compound of formula (II) where X, L, R, R, R, n, Y and R are as defined above, and oxidation involves treating a compound of formula (II) with urea hydroperoxide and trifluoroacetic anhydride .2. The method of claim 1, wherein X is NO, CN, or CONH. 3. The method of claim 1, wherein Y is CF or Cl. 4. A method according to claim 1, wherein R and R independently represent a hydrogen atom, methyl or ethyl. The method of claim 1, wherein X, R, R, n, Y, and R are as defined above, R is CH, n = 1-3, L is a single bond, the compound of formula (I) has the structure and compound of formula (II) has a structure6. The method of claim 5, wherein X is NO, CN or CONH, Y is (C-C) haloalkyl, R and R are individually hydrogen, methyl, ethyl, fluoro, chloro or bromo and n is an integer from 1 to 3.7. The method of claim 6, wherein X is NO, CN or CONH, Y is CF, R and R are individually hydrogen, methyl or ethyl, and n is an integer from 1 to 3.8. The method of claim 1, wherein X, R, R, n, Y, and R are as defined above, R, S, and L taken together form a saturated 5 membered ring, a compound of formula (I) has a structure, and a compound of formula ( II) has a structure. 9. The method of claim 1, further comprising carrying out oxidation in a polar solvent. The method of claim 9, wherein the polar solvent is selected from the group consisting of dichloromethane, tetrahydrofuran, ethyl acetate, acetone, dimethylformamide, acetonitrile and dimethyl sulfoxide. |
