, (2018/09/21)
PROBLEM TO BE SOLVED: To provide a novel method for producing a triazole compound useful as a pharmaceutical intermediate. SOLUTION: A production method includes reacting a lactic acid derivative with thionyl chloride, then reacting it with 1,3-difluoro benzene in the presence of Al chloride to obtain a ketone derivative, which is turned into an olefin with a Wittig reagent to be derived into compound (2), and it is then turned into an epoxy and a triazole to be derived into compound (1).

Page 9, (2010/11/30)
An epoxytriazole derivative (V) useful as an intermediate for anti-fungal agents and an intermediate therefor having high quality can be produced economically and efficiently by the following industrial means. A compound of the following formula (I) is reacted with trimethyloxosulfonium salt and the like in the presence of a base to give compound (II), this compound is converted to compound (IV), and this compound is reacted with 1,2,4-triazole in the presence of a base. wherein Ar is a phenyl group optionally substituted by 1 to 3 halogen atom(s) or trifluoromethyl group, R is a hydrogen atom or lower alkyl group, and X is a leaving group.

Stereocontrolled synthesis of an optically active triazolylmethyloxirane 2, an important intermediate for the preparation of antifungal oxazolidine compounds 1, was achieved by two methods using L-lactic acid as a starting material. The key intermediate ketone 6 used in the procedures also served for the synthesis of the enantiomer of 2 and the corresponding diastereomeric epoxide.
