An optical pure itraconazole key intermediate and synthetic method and by the intermediate synthesis of optically pure itraconazole method

The invention disclsoes an optically pure itraconazole key intermediate and synthetic method thereof, and a method for synthesizing the optically pure itraconazole from the intermediate. The method of the invention uses 1-(2,4-dichlorobenzene)-2-(1-methylene-1,2,4-triazole)-1-ketone for preparing the optically pure itraconazole key intermediate, and the optically pure itraconazole key intermediate is used for the preparation of optically pure itraconazole. The method uses easily available raw materials, not only reduces the production cost, but also obtains the product with high purity; through the control of the optical purity of the key intermediate compound VII, the optical purity of the target product itraconazole can be effectively controlled; therefore, the invention has with industrial value.

Stereoselective Syntheses of (+)- and (-)-Terconazole

The recently described cis-benzoates (2R,4R)- and (2S,4S)-2 were transformed into (+)- and (-)-terconazole, respectively by reaction with 1H-1,2,4-triazole followed by hydrolysis to give alcohols (+)- and (-)-3 which were mesylated and reacted with phenol
