    • Provided is an industrially advantageous method for producing optically active alcohols in high yields from ketones of various structures by using an inexpensive chiral catalyst. The method of the present invention for producing optically active alcohols comprises reducing a ketone in the presence of an iridium(III) complex having a chiral prolinamide compound as a ligand. The ketone is preferably a compound represented by formula [I]:

      (wherein R 1 and R 2 are different from each other, and each represent an optionally substituted straight or branched alkyl group, an optionally substituted cycloalkyl group, an optionally substituted aryl group, an optionally substituted heteroaryl group, an optionally substituted aralkyl group, an optionally substituted heteroarylalkyl group, an optionally substituted alkenyl group or an optionally substituted alkynyl group, and
      R 1 and R 2 may be bound to each other at any appropriate position to form a ring, the ring optionally containing one or more atoms which may be the same or different and are selected from an oxygen atom, an optionally substituted nitrogen atom and a sulfur atom, and optionally being condensed with an aromatic or hetero-aromatic ring).
    • 通过使用便宜的手性催化剂,提供了从各种结构的酮生产光学活性醇的工业上有利的方法。 本发明用于制备光学活性醇的方法包括在具有手性脯氨酰胺化合物作为配体的铱(III)络合物的存在下还原酮。 酮优选为式[I]表示的化合物:(其中R 1和R 2彼此不同,各自表示任选取代的直链或支链烷基,任选取代的环烷基,任选取代的芳基, 任选取代的杂芳基,任选取代的芳烷基,任选取代的杂芳基烷基,任选取代的烯基或任选取代的炔基,并且R 1和R 2可以在任何适当位置彼此结合形成环 所述环任选地含有一个或多个可以相同或不同并且选自氧原子,任选取代的氮原子和硫原子,并且任选地与芳族或杂芳族环缩合的原子)。
