title: Where is the Oxygen? Structural Analysis of α-Humulene Oxidation Products by the Crystalline Sponge Method.
abstract: Crystal structures of α-humulene, a cyclic sesquiterpene, and its oxidized subproducts, were analyzed by the crystalline sponge method. Regio- and stereochemistry, including absolute configuration when a chiral oxidant was applied, and the stable conformations of all the scaffold-related compounds were successfully determined for samples on a 5-50 μg scale.
