Abstract

A trimethylsilyl (SiMe3) group is the basis of a strategy that emulates the three fundamental proposed processes in ladder polyether biosynthesis: chain homologation, stereoselective epoxidation (> 95% ee or> 95: 5 dr), and endo-selective, stereospecific (inversion) hydroxyepoxide cyclization (> 95: 5 endo: exo,> 95% dr). A tris-THP was synthesized in 18 total operations from commercial materials using this approach.
