摘要:A synthesis method for a 7-ketolithocholic acid is prepared from a new intermediate I-1. According to the method, phytosterol degradation product bisnoralcohol is used as a starting material, and the 7-ketolithocholic acid or the intermediate thereof is obtained by means of an oxidation reaction, a Knoevenagel reaction (or wittig reaction), hydrogenation, a ketal protection reaction, an allylic oxidation reaction, ketal removal protection, and the hydrogenation.

摘要:A method for modifying ethylenic unsaturation in a triglyceride. One or more unsaturated fatty acyl moieties present in the triglyceride are substituted with a lactone or ketone moiety via a electron acceptor mediated reaction. The resulting reaction products are useful, for example, as lubricants, metalworking fluids, mold release agents, hydraulic fluids, or dielectric fluids, or as components of lubricants, metalworking fluids, mold release agents, hydraulic fluids, or dielectric fluids, and intermediates for polymer synthesis.
