The disclosure provides therapeutic compositions (i.e., therapeutic agents) and methods of preventing or treating Friedreich's ataxia in a mammalian subject, reducing risk factors, signs and/or symptoms associated with Friedreich's ataxia (e.g. Complex I deficiency), and/or reducing the likelihood or severity of Friedreich's ataxia. The disclosure further provides novel intermediates for the production of said therapeutic compositions and related reduced versions of said therapeutic compositions, which reduce forms may also be used as therapeutic agents (or prodrugs of the therapeutic agent(s)).
SEPARATION OF CHIRAL ISOMERS BY SFC

Page/Page column 34; 35, (2016/12/22)
The present invention relates to the field of separating chiral isomers from each other. Particularly, it relates to the field of separating of chiral isomers of chromane or chromene compounds, particularly tocopherols, 3,4-dehydro-tocopherols and tocotrienols, as well as the protected forms thereof. It has been found that the use of supercritical carbon dioxide as mobile phase combined with the very specific chiral phase as stationary phase leads to a very efficient separation of the individual chiral isomers. As the method is very efficient and fast combined with advantageous in view of ecology it is of big industrial interest.
Chemoenzymatic synthesis of both enantiomers of α-tocotrienol

The stereoselective acylation of the achiral chromanedimethanol derivative 1 by vinyl acetate in the presence of Candida antarctica lipase B gave the (S)-monoester 2 in high enantiomeric purity (ee ≥ 98%). Enzymatic hydrolysis of diesters of compound 1 failed to give (R)-monoester 2 in good yield and high ee. Thus, both enantiomers of α-tocotrienol were synthesized from the (S)-monoester 2.
