Uncontrolled substitution patterns during the synthesis of complex arenes lead to poor isomeric purity. Achieving precise site-selectivity reduces waste and simplifies downstream purification in multi-step synthesis.

Inconsistent configuration at the sulfur atom during synthesis leads to racemic mixtures. Precise stereogenic control enables the production of enantiopure bioactive molecules.

Inconsistent spatial arrangement of atoms during synthesis leads to ineffective isomers. Achieving high enantiomeric or diastereomeric excess ensures biological activity and reduces chemical waste.

Insufficient control over enantiomeric and diastereomeric ratios during synthesis leads to chemical waste and reduced biological activity. Achieving high isomeric enrichment ensures precise molecular targeting and regulatory compliance.

The synthesis of oxime derivatives often results in racemic mixtures or insufficient optical enrichment. Achieving high enantiomeric excess is critical for the biological efficacy and safety of pharmaceutical compounds.
