Domino Reactions in Natural Product Synthesis
Research Guide
What is Domino Reactions in Natural Product Synthesis?
Domino reactions in natural product synthesis are one-pot multi-component cascades that combine cyclization, cycloaddition, and functionalization steps to construct complex polyketide and alkaloid frameworks with step economy.
These reactions enable efficient total synthesis by minimizing synthetic steps and waste. Researchers optimize conditions for cascades targeting natural products like β-lapachone derivatives. Over 2 papers document approaches since 2006.
Why It Matters
Domino cascades streamline total synthesis of bioactive natural products, reducing purification needs and costs in pharmaceutical development (Prado, 2016). They support scalable production of lapachone analogs for anticancer applications. Efficiency gains aid green chemistry in alkaloid and polyketide synthesis.
Key Research Challenges
Reaction Selectivity Control
Achieving high regioselectivity in multi-step cascades remains difficult due to competing pathways. Optimization of conditions often requires extensive screening (Prado, 2016). Side products reduce yields in complex frameworks.
Catalyst Compatibility Issues
Catalysts must endure sequential transformations without deactivation. Mismatched compatibilities disrupt one-pot efficiency. Literature shows limited examples for polyketide targets.
Scalability Limitations
Lab-scale cascades fail at larger volumes due to heat/mass transfer issues. Few reports address gram-scale natural product synthesis. Process engineering gaps persist.
