baker's yeast mediated reduction of sulphur-functionalised methacroleins 11, 15 and 18 leads to the preparation of the bifunctional methyl branched C4 chiral synthons 6 and 7. The stereochemical aspects of the biohydrogenation have been investigated. Both the oxidation state of sulphur and the isomeric position of the double bond affected the enantioselectivity of the reduction strongly, thus, offering

硫的氧化态和双键的异构体位置都强烈影响还原的对映选择性,因此,提供了进入6和7两种对映体形式的途径。
