✦ Synopsis
Treatment of 4,6-diacetate 3 with tert-butyl hydroperoxide gave the Sr~2' product 6 in high yield, the formation of which presumeably involves an intermediary nitronate. The thus prepared 6 reacted with nucleophiles to afford 2,3-anhydro derivatives having the talo configuration.

Reactions of the title compounds with several nucelophiles suggested that the ring oxygen atom (0-5) accelerated the reactivity of the nitro alkene moiety, but scarcely affected the stereoselectivity of the nucleophilic attack.
