METHOD FOR PRODUCING PITAVASTATIN CALCIUM

Production of pitavastatin calcium safely on an industrial scale with a high yield and high selectivity at low cost. A method of producing pitavastatin calcium including step (i) for acetalizing a compound represented by the formula (1) to give a compound represented by the formula (3), step (ii) for reacting a compound represented by the formula (3) with an acid to give a compound represented by the formula (4), and step (iii) for hydrolyzing a compound represented by the formula (4) and reacting same with a calcium compound.

Process for producing (3R,5S)-(E)-7-[2-cyclopropyl-4-(4-fluorophenyl)-quinolin- 3-yl]-3, 5-dihydroxyhept-6-enic acid esters

A process for producing a compound represented by the following formula (IV): (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): (wherein R is as defined in the formula); a compound represented by the following formula (II): (wherein R is as defined in the formula); and a compound represented by the following formula (III): (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.
