Provided is a method capable of industrially producing optically active (S)-7-hydroxy-6-methylheptan-2-one and its precursor simply and efficiently. The production method, allows a R-body preferentially hydrolyzable Aspergillus microorganism-derived esterase to act on a 2-methyl-6-oxoheptanoate (II), to produce an optically active (S)-2-methyl-6-oxoheptanoate (III).
the active pharmaceutical ingredient for clinical trials, exploring enzymatic and microbial methods to produce chiral building blocks on a multi‐kilogram scale. The three building blocks were identified as key intermediates in the synthesis and needed to be produced with high optical purity in yields higher than those previously published. The improved syntheses of two of these building blocks are

-fragments of epothilones and derivatives thereof, in which a C1-C6-fragment is linked with a C7-C12-fragment to a C1-C12-fragment, and the latter then is reacted with a C13-15-fragment to form the C1-C15 initial epothilone product that is to be produced. The thus obtained C1-C15 initial epothilone products can be reacted according to known methods to form the actual active ingredients. In addition, the invention relates to the corresponding C1-C12-fragments.
