Abstract
Metal-free homoallylic oxygen-directed intramolecular hydroboration is reported. Regioselectivities from 20: 1 to 82: 1 favoring the 1, 3-dioxy-substituted products have been achieved using Me2S· BH3/TfOH followed by standard oxidative workup. Branching at the C5 position improves regioselectivity.
