Stereocontrolled syntheses of an optically active triazolymethyloxirane 2, an important intermediate for the preparation of anifungal 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.
以L-乳酸为起始原料,通过两种方法实现了光学活性三唑甲基环氧乙烷2的立体控制合成,三唑甲基环氧乙烷2是制备真菌恶唑烷化合物1的重要中间体。该过程中使用的关键中间体酮 6 也用于合成 2 的对映体和相应的非对映体环氧化物。
