ABSTRACT:
The present invention relates to an asymmetrically modified borohydride type compound obtained by reacting an optically active amino alcohol represented by the formula, ##STR1## or its salt with an acid with a borohydride compound; its production method; and a method for producing an optically active alcohol derivative useful as fungicides, herbicides or plant growth regulators and represented by the formula, ##STR2## which comprises asymmetrically reducing a ketone compound represented by the formula, ##STR3## with the asymmetrically modified borohydride type compound.
