摘要 |
The present invention relates to a method for producing optically active alcohol derivatives, which are useful as fungicides, herbicides or plant growth regulators, represented by the formula, <IMAGE> by carrying out the asymmetric reduction of a ketone compound represented by the formula, <IMAGE> with a boron hydride-reducing agent modified with an optically active amino alcohol represented by the formula, <IMAGE> and also relates to the boron hydride type compound obtained by reacting the above optically active amino alcohol with a boron hydride compound and its production method. |
