Abstract
We demonstrate that a functional reversal of the β-oxidation cycle can be used as a metabolic platform for the synthesis of alcohols and carboxylic acids with various chain lengths and functionalities. This pathway operates with coenzyme A (CoA) thioester intermediates and directly uses acetyl-CoA...

Abstract
Cyclofructans cannot be used as chiral stationary phases for GLC in their native states. This is due to their high melting points and their inability to be solubilized in other liquid stationary phases. However, when cyclofructans are derivatized (via the 3-, 4-, or 6-hydroxyl groups) they can then...
