Synthesis of Oxabicyclo[3.2.1]octan-3-ol Scaffold via Burgess Reagent Mediated Cyclodehydration of δ-Diols under Acidic Conditions.

Dehydrative cyclization of δ-diols was achieved by using the Burgess reagent under mild conditions to furnish a novel oxabicyclo[3.2.1]octan-3-ol scaffold. The stereochemistry of the generated oxabicyclic compounds was assigned based on single X-ray crystallography and 2D-NMR experiments.
