Total syntheses of natural pseurotins A, F2, and azaspirene

We describe the total syntheses of natural pseurotins A and F2, inhibitors of chitin synthase, both of which possess an unusual 1-oxa-7-azaspiro[4.4]non-2-ene-4,6-dione ring system. The total syntheses of these spiro-hetereocyclic natural produ

Stereocontrolled synthesis of a highly functionalized 1,7-dioxaspiro[4.4]Nonane derivative related to antibiotic pseurotins

For a total synthesis of pseurotins, unusual heterospirocyclic antibiotics, a key intermediate (5), having a highly functionalized 1,7-dioxaspiro-[4.4]nonane structure, has been synthesized from diacetone D-glucose.
