Efficient asymmetric bio-epoxidation of electron-deficient [small alpha],[small beta]-unsaturated ketones was realized via a tandem reduction-epoxidation-dehydrogenation cascade, which proceeds in a switchable manner to afford either chiral epoxy ketones or allylic epoxy alcohols...
Antifungal carbinols having the formula
wherein:
R and R¹ are independently H or CH₃;
X and Y¹ are independently H, 1 to 3 halogens or CF₃; and
X′ and Y are independently H, CH₃, CF₃, OCF₂H, OCH₃ or SCH₃
and their agriculturally and pharmaceutically suitable salts are useful as plant disease control agents.
The compounds may be made e.g. by reacting an appropriate oxirane of formula:
with triazole or its alkali metal salt.
