| titleOfInvention | IMPROVED METHOD FOR PRODUCING OXAZOLIDINE-PROTECTED AMINODIOL COMPOUNDS USED AS FLORPHENICOL INTERMEDIATES |
| abstract | 1. A method of obtaining a compound of formula XI:! ! where R1 is hydrogen, methylthio, methylsulfoxy, methylsulfonyl, fluoromethylthio, fluoromethylsulfoxy, fluoromethylsulfonyl, nitro, fluorine, bromine, chlorine, acetyl, benzyl, phenyl, halogenated phenyl, alkyl with 1-6 carbon atoms, haloalkyl with 1-6 carbon atoms , C 3-8 cycloalkyl, C 2-6 alkenyl, C 2-6 alkynyl, C 1-6 alkoxy, C 1-6 aralkyl, C 2-6 aralkenyl or heterocyclic a group with 2-6 carbon atoms; and ! R7 is hydrogen, C 1-6 alkyl, C 1-6 haloalkyl, C 1-6 dihaloalkyl, C 1 trihaloalkyl, C 3-8 cycloalkyl, C 3-8 cycloalkyl , cyclodihaloalkyl with 3-8 carbon atoms, cyclotrihaloalkyl with 3-8 carbon atoms, alkenyl with 2-6 carbon atoms, alkynyl with 2-6 carbon atoms, alkoxy with 1-6 carbon atoms, aralkyl with 1-6 carbon atoms, aralkenyl with 2-6 carbon atoms, heterocycle with 2-6 carbon atoms, benzyl, phenyl or phenylalkyl, where the phenyl ring may be substituted with one or two halogens, alkyl with 1-6 carbon atoms or alkoxy group with 1-6 carbon atoms, providing: ! a) reaction of a compound of formula VI! ! where R1 is the same as defined above, and! R5 is hydrogen, alkyl with 1-6 carbon atoms, cycloalkyl with 3-8 carbon atoms, benzyl, phenyl or alkylphenyl with 1-6 carbon atoms, in a reaction vessel with a reducing agent in an alcoholic solvent to form an aminodiol compound of formula VII:! ! where R1 is the same as defined above; ! b) |
