was observed was at around 540, independent of the structure of the alpha-hydroxyketone. The oxygen in alpha-position to the ketone seems to play an important role in the enantioselection as well as a phenyl ring or a rigid cis-conformation. The dependence of the enantiomeric excess on the...

The present invention is to a method for the preparation of α - hydroxyketone directed. The present method operates enzymatically and allows the desired compounds in to obtain high enantiomer concentrations.The present invention also provides a correspondingly modified whole cell catalyst, and its use...
Obtained from terpin hydrate by splitting off water; from pentane tricarboxylic acid by cyclization, followed by esterification to the hydroxy ester, then the unsaturated ester and Grignard to terpineol; also from isoprene and methyl vinyl ketone, using methyl magnesium iodide. ...
The absence of the ketone function in the dihydro-iso-alpha-acids has the following consequences: • The Norrish Type I cleavage in the photochemical breakdown is no longer possible, effectively rendering the dihydro-iso-alpha-acids photostable. • The retro-aldol reaction under basic conditions...
