Syn. Route	4

Route 1 the synthesis of deuterated sevoflurane has been described:the methylation of 1,1,1,3,3,3-hexafluoroisopropanol (i) with deuterated dimethylsulfate by means of 10% aqueous naoh yields the corresponding deuterated methyl ether (ii), which is then fluorinated with brf3. List of intermediates No. dodecanoyl chloride (ii) 3-oxocyclohexanecarboxylic acid (i) dibenzyl 2-[(1r)-3-oxocyclohexyl]malonate (ii) Reference 1:     baker, m.t.; chiang, c.-k.; tinker, j.h.; synthesis of fluoro-dideutero-methyl 1,1,1,3,3,3-hexafluoro-2-propyl ether (deuterated sevoflurane). j label compd radiopharm 1993, 33, 9, 801. Route 2 1,1,1,3,3,3-hexafluoro-2-propyl methyl ether (i) is photochlorinated with cl2 giving 1,1,1,3,3,3-hexafluoro-2-propylchloromethyl ether (ii), which is then fluorinated with kf in tetrahydrothiophene-1,1-dioxide. List of intermediates No. dodecanoyl chloride (i) 2-hydroxyethyl laurate (ii) Reference 1:     regan, b.m.; longstreet, j.c.; halogenmethyl-1,3-polyhalogen-2-propyllathen und verfahren zu deren herstellung sowie diese enthaltende anasthesie-mittel. de 1954268; fr 2021695; gb 1250928; nl 6916076 . Reference 2:     sungurbey, k.; castaner, j.; sevoflurane. drugs fut 1976, 1, 6, 307. Route 3 compound is obtained by reaction of 1,1,1,3,3,3-hexafluoro-2-propanol (i) with formaldehyde and hf in hot sulfuric acid. List of intermediates No. 3-oxocyclohexanecarboxylic acid (i) Reference 1:     coon, c.l.; simon, r.l. (baxter international inc.); method of synthesizing fluoromethylhexafluoroisopropyl ether. us 4469898 . Route 4 a new method for the preparation of sevoflurane has been described: reaction of 1,1,1,3,3,3-hexafluoro-2-propanol (i) with 1,3,5-trioxane (ii) and alcl3 gives the chloromethyl ether (iii), which is then fluorinated with kf in hot polyethylene glycol (peg-400). List of intermediates No. 2-hydroxyethyl laurate (iii) 3-oxocyclohexanecarboxylic acid (i) 3-(2,3-dimethylphenoxy)phenyl methyl ether; 1-(3-methoxyphenoxy)-2,3-dimethylbenzene (ii) Reference 1:     schure, r.m.; behme, c.; ramakrishma, k.; bieniarz, c.; a safe and efficient process for the synthesis of the inhalation anesthetic sevoflurane. org process res dev 2000, 4, 6, 581.
