Abstract
A mixture of cis- and trans-2-(6-m-methoxyphenyl-3-oxohexyl)-2,4-dimethylcyclopenta-1,3-dione (±)-10 was synthesized and incubated with Schizosaccharomyces pombe (NRRL Y-164) to give (+)-11, (+)-12, (−)-13, and (−)-14 in 19, 13, 22, and 16% yields, respectively. Chromic acid oxidation of these microbiologically reduced products gave (−)-10a, (+)-10b, (+)-10a, and (−)-10b, respectively.
