Natural products as pesticides: Two examples of stereoselective synthesis
摘要:
The strategy and synthetic efforts leading to efficient stereoselective syntheses of thiangazole, a tris-thiazolinyl-oxazole metabolite isolated from Poly-angium spp., and of hydantocidin, a spironucleoside metabolite isolated from Streptomyces hygroscopicus, are discussed.

The naturally occurring spironucleoside (+)-hydantocidin 1 was synthesized from 1,2:3,4-di-O-isopropylidene-D-psicofuranose using a new oxygen-bridged intramolecular Vorbruggen coupling of the N-hydroxyurea 5 in presence of a catalytic amount of trimethylsilyltriflate.
