Low selectivity and degradation during the formation of volatile isoprenoid precursors. Stabilizing these intermediates ensures higher yields of downstream fragrance and vitamin precursors.

Inefficient chemical conversion pathways for complex bicyclic and quinone structures. Improving yield reduces waste and manufacturing costs for bioactive precursors.

Uncontrolled reduction of multiple functional groups leads to poor product purity. Achieving high selectivity prevents the formation of unwanted side-products in complex unsaturated molecules.
