    • Compounds represented by general formula (I), pharmaceutically acceptable acid addition salts thereof, or hydrates of the same; drugs containing these compounds; medicinal compositions containing these compounds together with pharmaceutically acceptable carriers; and 2-amino-2-(2-(4-(1-hydroxy-5-phenylpentyl)phenyl)ethyl)propane-1,3-diol or 2-amino-2-(2-(4-formylphenyl)ethyl)-propane-1,3-diol optionally protected at the amino and/or hydroxy group or salts thereof, each useful as an intermediate in synthesizing the above compounds. In said formula, R , R , R and R represent each hydrogen or acyl. Because of having little toxicity, high safety and excellent immunosuppressive effects, these compounds are useful as preventives or depressants for rejection reactions in organ or bone marrow transplantations and preventives or remedies for various autoimmune diseases, various allergic diseases, etc.

    • Accordingly, the present invention provides a process for the preparation of a compound of formula (I) or a single enantiomer thereof, or a salt or a solvate thereof, wherein W is a chiral auxiliary or hydrogen and P and P are each independently selected from hydrogen or a protecting group, which comprises: a) treatment of a compound of formula (II), or a salt or a solvate thereof, wherein W is a chiral auxiliary and P and P are each independently selected from hydrogen or a protecting group, with a compound of formula (III); b) treatment of the resulting product with a reducing agent; c) if required, deprotection to yield the compound of formula (I), or a salt or solvate thereof. In particular there is provided a process for producing a substantially pure single enantiomer of salmeterol.
    • 因此,本发明提供了制备式(I)化合物或其单一对映异构体或其盐或溶剂合物的方法,其中W是手性助剂或氢,P 1和P 2 其各自独立地选自氢或保护基,其包括:a)处理式(II)化合物或其盐或溶剂合物,其中W是手性助剂,P 1和P 2 各自独立地选自氢或保护基,与式(III)的化合物反应; b)用还原剂处理所得产物; c)如果需要,脱保护得到式(I)化合物或其盐或溶剂合物。 特别地,提供了生产沙美特罗基本上纯的单一对映异构体的方法。
