Enzyme-catalysed approach to the preparation of triazole antifungals: synthesis of (-)-genaconazole

The work describes a new enzyme-mediated approach to optically active epoxide (2R,3S)-6, which is an important key intermediate in the preparation of single enantiomers of chiral azole antifungals. The conversion of (2R,3S)-6 into (-)-genaconazole is reported as an example of its synthetic relevance.

Triazole antifungals. III. Stereocontrolled synthesis of an optically active triazolylmethyloxirane precursor to antifungal oxazolidine derivatives

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.
