A short synthesis of a highly functionalized AB taxane ring system is described which features the introduction of the C-9 and C-10 oxygen functions on the eight-membered B ring using 1,4-dioxene.

Oxidation of various alkyldioxens with dimethyldioxirane is described. While pure epoxides were isolated from 4-dioxenylcyclohexanone 10 and diether 9, vinyldioxenes 11–14 gave the corresponding epoxide rearrangement products, α-ketal aldehydes 20–24, in excellent yields.
