A Three‐Step Chemoenzymatic Cascade Synthesis of Miconazole Analogues Based on the Asymmetric Synthesis of β‐Heteroaryl Amino Alcohols via Ketoreductases
isolation of ketone and alcohol intermediates, and avoids the use of metal catalysts in the synthesis of chiral miconazole analogues. Furthermore, we successfully scaled up the preparation of (S)-miconazole, achieving a 30% isolated yield and >99% ee. This method presents a novel synthetic approach for production chiral ether drugs and chiral β-heteroaryl amino alcohols, offering new possibilities in pharmaceutical
