Depending on the choice of lipase, 1,3‐di‐O‐benzyl‐myo‐inositol (1) either undergoes desymmetrization to form l‐(+)‐6‐O‐acetyl‐1,3‐di‐O‐benzyl‐myo‐inositol (with Lipozyme RM‐IM or Lipozyme TL‐IM), or is transformed into the meso 5‐O‐acetyl derivative 3 (with Novozym 435).
The present invention relates to an isolated DNA molecule encoding a fagopyritol synthase. A method for producing a fagopyritol, an insulin mediator, an insulin mediator analog, an insulin mediator homolog, or an insulin mediator inhibitor is also described. The method includes providing a fagopyritol synthase, providing a substrate comprising a galactosyl donor and a galactosyl acceptor, and combining the fagopyritol synthase with the substrate under conditions effective produce a fagopyritol, an insulin mediator, an insulin mediator analog, an insulin mediator homolog, or an insulin mediator inhibitor.

A practical, five-step synthetic sequence for conversion of myoinositol into enantiomerically pure (+)- and (-)-ononitols in 17% and 18% overall yield, respectively, has been developed.

The invention provides methods and compositions for making a dicotyledonous plant that is susceptible to Phymatotrichopsis Root Rot (PRR) more resistant to PRR, by metabolic engineering of the plant's flavonoid and isoflavonoid biosynthetic pathways. Thus, methods for increasing the synthesis and accumulation of medicarpin and/or 7,4′-dihydroxyflavone in plants such as alfalfa are provided.
