A compound represented by the general formula:
wherein R1 and R2 denote a halogen atom or hydrogen atoms; R3 means a hydrogen atoms or lower alkyl group; r and m stand for 0 or 1; A is N or CH; W denotes an aromatic ring or a condensed ring thereof; X means another aromatic rings, an alkanediyl group, an alkenediyl group, or an alkynediyl group; Y stand for -S-, etc.; Z denotes a hydrogen atom, etc., or a salt thereof, and intermediates thereof or a salt thereof as well as processes for the preparation thereof, and pharmacetical composition suitable for use as an antifungal agent.
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
2-Amino-4-aryl-5-(1H-1,2,4-triazol-1-yl)thiazole derivatives were synthesized from the reaction of a-bromo substituted acetophenone and thiourea. The structures were confirmed by elemental analysis, H-1 NMR and single crystal X-ray diffraction analysis. Biological evaluation showed that some of them possess antifungal and plant growth regulatory activities.
