  • Method of making teprenone
    Publication number: 20040249219
    Abstract: The invention is directed to an efficient and economical method of making teprenone. Teprenone is synthesized by converting geranylgeraniol to teprenone by a novel route. The method of synthesis can begin with geranylgeraniol obtained from a biological source such as fermentation of a microorganism capable of producing geranylgeranyl or enzymatic synthesis in a cell free system to produce predominantly the 5E isomer of teprenone. The chemical synthesis proceeds with retention of configuration such that the teprenone produced has the isomeric configuration of the geranylgeraniol starting material.

  • Method of vitamin production
    Publication number: 20030125573
    Abstract: The invention provides a method of producing &agr;-tocopherol and &agr;-tocopheryl esters. The method comprises using a biological system to produce farnesol or geranylgeraniol. Then, the farnesol or geranylgernaiol is chemically converted into &agr;-tocopherol or an &agr;-tocopheryl ester.
