A process for producing a compound represented by the following formula (IV):
1
(wherein R denotes a hydrogen atom, an alkyl group, or an aryl group), comprising reducing a compound selected from the group consisting of:
a compound represented by the following formula (I):
2
(wherein R is as defined in the formula);
a compound represented by the following formula (II):
3
(wherein R is as defined in the formula); and
a compound represented by the following formula (III):
4
(wherein R is as defined in the formula), by reacting the compound with a cell of a microorganism and/or a cell preparation thereof capable of stereo-selectively reducing a keto group.
