Recent Advances in Amino Acid-Based Phosphine Catalysts and Their Applications in Asymmetric Reactions

Аннотация

Amino acid-based catalysts have been intensively researched in recent years. Amino acid-derived phosphines possess high nucleophilicity and exhibit unique catalytic activities in asymmetric synthesis. L-Threonine and valine are most utilized natural amino acids in the preparation of chiral phosphines. The efficient and versatile chiral phosphine catalysts are applied in a wide range of reactions such as MBH reaction, Rauhut–Currier reaction, Michael addition, [4 + 2]-annulation, [3 + 2]-annulation, 1,4-dipolar cycloaddition. They are also widely used in the construction of core structures of natural products. Amino acid-based phosphine catalysts and their applications in asymmetric synthesis are summarized.
