Payne rearrangement route to the optically active oxirane precursor for the preparation of triazole antifungals

Optically active epoxide 1, an important intermediate for the preparation of antifungal triazole-amides 2, was synthesized starting from the (S)-lactic acid-derived ketone 9 and taking advantage of the Payne rearrangement of the epoxyalcohol 8.
