Methyl trans-chrysanthemate has been prepared in few steps from isopropylidenediphenylsulfurane and methyl (E)-3-(3,3-dimethyloxiran-2-yl)prop-2-enoate. The latter was obtained from methyl 4-oxobutenoate or 3-methylbut-2-en-1-ol. The Sharpless catalytic epoxidation reaction allows an asymmetric version of this transformation.
