An enantioselective synthesis of (-)-nonactic acid (2a) and (+)-8-epi-nonactic acid (2b) is described. The microbial reduction of the dl-ketone 3 with baker's yeast gave two easily separable diastereomeric alcohols 11a and 11b, each in over 97% ee. These alcohols were converted to 2a and 2b in 4 steps.
描述了 (-)-壬酸 (2a) 和 (+)-8-表壬酸 (2b) 的对映选择性合成。dl-酮 3 与面包酵母的微生物还原得到两种易于分离的非对映异构醇 11a 和 11b,每一种都超过 97% ee。这些醇分 4 个步骤转化为 2a 和 2b。
